refactor: Add dedicated setup-db job to eliminate cache race condition (#26171)

* refactor: Add dedicated setup-db job to eliminate cache race condition

- Create new setup-db.yml workflow that runs cache-db action
- Update pr.yml to add setup-db job that runs before all E2E jobs
- Update integration-test, e2e, e2e-api-v2, e2e-app-store, e2e-embed,
  and e2e-embed-react jobs to depend on setup-db instead of build-api-v1
- Add setup-db to required job needs list and result check

This eliminates the race condition where multiple jobs could try to
write to the same database cache simultaneously.

* refactor: Remove DB parts from api-v1-production-build.yml

The database setup is now handled by the dedicated setup-db job,
so the postgres service and cache-db action are no longer needed
in the API v1 build workflow.

* Apply suggestion from @keithwillcode

* Made integration tests dependency consistent

* refactor: Remove unnecessary env vars from setup-db.yml

Only keep the env vars needed for database setup:
- CALENDSO_ENCRYPTION_KEY (for db-seed)
- DATABASE_URL / DATABASE_DIRECT_URL (for database connection)
- TURBO_TOKEN / TURBO_TEAM (for turbo caching)

* fix: Add back E2E_TEST_CALCOM_QA_* env vars needed by db-seed

These env vars are used by scripts/seed.ts to create the QA user
with Google Calendar credentials during database seeding.

* fix: Restore postgres service and cache-db to api-v1-production-build.yml

The API v1 build still needs a database to run properly. Restored the
postgres service and cache-db action, and added dependency on setup-db
so it waits for the database cache to be created first.

* E2E for API v2 no longer waiting on API v2 build

* Reordering the jobs by dependencies

* add GOOGLE_API_CREDENTIALS env var to setup db

* Added back all env vars to setup-db

* fix: Include commit SHA in cache-db key to invalidate cache on new commits

* refactor: Strip back setup-db.yml env vars to minimal set needed for db-seed
