Allow app config link to target config by client ID

[gonzaloriestra]

WHY are these changes introduced?

The interactivity audit found that app config link could not use --client-id and --config together, leaving a prompt in otherwise scripted linking flows.

WHAT is this pull request doing?

• Allows app config link to pair --client-id with --config.
• Adds command coverage and refreshes generated command docs.

How to test your changes?

• pnpm vitest run packages/app/src/cli/commands/app/config/link.test.ts
• pnpm refresh-manifests
