Update bulk action endpoints for database services:
- Use `/api/trpc/redis.start` and `/api/trpc/redis.stop` for Redis
- Use `/api/trpc/postgres.start` and `/api/trpc/postgres.stop` for PostgreSQL
- Retain `/api/trpc/compose.start` and `/api/trpc/compose.stop` for Docker Compose services
Tested with a project including Gitea, Redis, and PostgreSQL. Bulk start/stop operations now function correctly for all service types.
Closes#1626
