fix(webapp): give PAT-authenticated requests user.id in sentry events

createLoaderPATApiRoute was the only authenticated builder not stamping
the scope with the request's user — PAT auth carries `userId` but not
an AuthenticatedEnvironment, so the other builders' `tenantContext.run`
pattern doesn't apply. Enrich the scope established by the Express
middleware with the user id so Sentry events from PAT routes get
user-level attribution.
