feat(webapp): management API for orgs, projects, members, and settings (#4146)

## Summary

Adds a set of PAT-authenticated management API endpoints so orgs,
projects, members/invites, environment variables, and a few
project/environment settings can be managed programmatically (scripting,
automation) rather than only through the dashboard. Each route is a thin
wrapper over the **existing** service the dashboard already uses, with
the same authorization applied at the route layer - no new business
logic.

## Endpoints

**Organizations**
- `POST /api/v1/orgs` - create an org (`createOrganization`)
- `PATCH /api/v1/orgs/:orgParam` - rename (title)
- `DELETE /api/v1/orgs/:orgParam` - soft-delete
(`DeleteOrganizationService`; keeps the active-subscription guard)

**Members & invites**
- `GET /api/v1/orgs/:orgParam/members` - list members + pending invites
- `DELETE /api/v1/orgs/:orgParam/members/:memberId` - remove a member
(last-member guarded)
- `POST /api/v1/orgs/:orgParam/invites` - invite by email
(`inviteMembers`, sends the invite email)
- `DELETE /api/v1/orgs/:orgParam/invites/:inviteId` - revoke an invite

**Projects**
- `PATCH /api/v1/projects/:projectRef` - rename
(`ProjectSettingsService`)
- `DELETE /api/v1/projects/:projectRef` - soft-delete
(`DeleteProjectService`)
- `PUT /api/v1/projects/:projectRef/default-region` - set the default
region by worker-group name (`SetDefaultRegionService`)
- project GET/list now return `defaultRegion` (worker-group name, or
null when unset)

**Environments**
- `POST /api/v1/projects/:projectRef/:env/pause` and `/resume`
(`PauseEnvironmentService`)
- `POST /api/v1/projects/:projectRef/:env/regenerate-api-key` - rotate
the env secret key (`regenerateApiKey`, RBAC `write:apiKeys`)
- env var create now accepts an optional `isSecret` flag

## Auth & authorization

- All routes authenticate with a **Personal Access Token**
(`Authorization: Bearer tr_pat_...`).
- Org/project routes are built on the PAT route builders in
`apiBuilder.server.ts`: `createLoaderPATApiRoute` (already existed) and
**`createActionPATApiRoute`** (added here - the loader builder had no
mutation counterpart). The builder runs auth, resolves the org/project
role-floor via `context`, and enforces a declarative `authorization`
block using the same RBAC actions the dashboard applies
(`manage:organization` / `read:members` / `manage:members` /
`manage:project`). Handlers keep a membership-scoped query as the floor,
so a non-member gets a 404. This also gives these routes `tenantContext`
user attribution (Sentry) and `ServiceValidationError`-to-status mapping
for free.
- **Membership floor (important).** The OSS RBAC fallback grants a
permissive ability, so `ability.can(...)` can't reject a non-member on
self-hosted. Every handler therefore resolves the target scoped to the
caller's membership (`members: { some: { userId } }`) → 404 for
non-members. `authorization` is the *role* gate; this is the *tenant*
gate. `resolveOrganizationForApiUser`
(`organizationApiAccess.server.ts`) is the org-tier version of the
existing `findProjectByRef` - org-addressed PAT routes are new, so no
such helper existed before.
- Env-tier routes reuse the existing `authorizePatEnvironmentAccess`
(`write:apiKeys`).

### What `createActionPATApiRoute` gives you

A route is pure declaration - the builder handles auth, RBAC,
validation, tracing, and error mapping:

```ts
export const action = createActionPATApiRoute(
  {
    method: "PUT",                          // one verb, or ["PATCH", "DELETE"] for multi-verb routes
    params: ParamsSchema,
    body: SetDefaultRegionRequestBody,      // zod-validated
    context: async ({ projectRef }) => {    // resolve the org for the RBAC role-floor
      const project = await prisma.project.findFirst({
        where: { externalRef: projectRef, deletedAt: null },
        select: { organizationId: true },
      });
      return project ? { organizationId: project.organizationId } : {};
    },
    authorization: { action: "manage", resource: () => ({ type: "project" }) },
  },
  async ({ params, body, authentication, ability }) => {
    // auth + authz already enforced. Just do the work.
    // `throw new ServiceValidationError("Region not found", 400)` → mapped to that status.
    return json({ ok: true });
  }
);
```

Handled for you, so handlers stay thin:

- **Method allowlist** - `method` accepts a verb or an array; any other
verb → `405` with an `Allow` header, *before* auth runs:
  ```ts
const allowedMethods = method ? (Array.isArray(method) ? method :
[method]) : undefined;
if (allowedMethods && !(allowedMethods as
string[]).includes(request.method.toUpperCase())) {
return json({ error: "Method not allowed" }, { status: 405, headers: {
Allow: allowedMethods.join(", ") } });
  }
  ```
- **PAT / user-actor auth** in a single roundtrip → `401` on
missing/invalid/revoked token.
- **RBAC** - `context` computes the caller's role-floor for the target
org/project; `authorization` gates it → `403` with a structured error
body.
- **Sentry attribution** - `tenantContext.enrich({ userId })` so events
from the handler carry the acting user.
- **Typed errors** - a thrown `ServiceValidationError` is mapped to its
`.status` (default 400); anything else → `500`, and expected boundary
errors are logged as `warn` (kept out of Sentry).
- **Validation** - params / query / headers / body are all zod-checked →
`400` with details.

## Notes for reviewers

- Everything wraps an existing service; the intent is API parity for
things that are currently dashboard-only, not new behaviour.
- `createActionPATApiRoute` is new shared infra (the PAT + RBAC mutation
builder that didn't exist). It's self-contained - the loader builder and
existing routes are untouched.
- `@trigger.dev/core` gets one additive field (`defaultRegion` on the
project response, optional/nullable for client-server version skew) -
changeset included, patch.
- `removeTeamMember`'s last-member guard is now atomic (Serializable
transaction via the `$transaction` helper, with retry), so the dashboard
and API both get it server-side. Added a `## Transactions` rule to
`apps/webapp/CLAUDE.md` (always use the `$transaction` helper);
migrating the remaining direct usages is tracked in TRI-11698.

## Open questions

- ~~Is PAT the right auth (vs OAT for automation)?~~ **Resolved: PAT.**
Organization Access Tokens are currently internal-only (used by the
image builder) and not user-accessible, so they can't back this yet.
- Should any of these be gated behind a flag or scope?
- Naming/shape of the routes.

 - **Always use `findFirst` instead of `findUnique`.** Prisma's `findUnique` has an implicit DataLoader that batches concurrent calls into a single `IN` query. This batching cannot be disabled and has active bugs even in Prisma 6.x: uppercase UUIDs returning null (#25484, confirmed 6.4.1), composite key SQL correctness issues (#22202), and 5-10x worse performance than manual DataLoader (#6573, open since 2021). `findFirst` is never batched and avoids this entire class of issues.
 
+## Transactions
+
+- **Always use the `$transaction` helper from `~/db.server`, never `prisma.$transaction` (or `$replica.$transaction`) directly.** The helper wraps the raw call with tracing (an OTEL span + an `isolation_level` attribute) and boundary logging for infrastructure errors (e.g. `PrismaClientInitializationError`) that the raw client swallows. Signature: `$transaction(prisma, name?, async (tx) => { ... }, options?)`.
+- Pass the isolation level via options as a string: `{ isolationLevel: "Serializable" }`. Reach for `Serializable` when a read-then-write must be atomic against concurrent transactions (e.g. a count-then-delete invariant); the loser of a race fails and can retry, which is the right trade for rare, correctness-critical paths.
+- The helper returns `R | undefined` — guard the result (`if (!result) throw ...`) when callers need a definite value.
+
+## PAT-authenticated API routes
+
+- **A PAT route must resolve its target org/project scoped to the caller's membership** (`members: { some: { userId } }`, or a helper like `findProjectByRef` / `resolveOrganizationForApiUser`). A PAT is user-scoped and can name any org/project by id/slug, and the OSS RBAC fallback ability is permissive — so `ability.can(...)` alone does NOT reject a non-member on self-hosted. The RBAC `authorization` gate enforces the *role*; the membership-scoped query is the *tenant* floor. Skipping it opens cross-org access on OSS.
+
 ## React Patterns
 
 - Only use `useCallback`/`useMemo` for context provider values, expensive derived data that is a dependency elsewhere, or stable refs required by a dependency array. Don't wrap ordinary event handlers or trivial computations.
