* refactor: improve usage table behavior to eliminate synchronous row locks
Replace synchronous INSERT...RETURNING with SELECT + async UPDATE pattern:
- Add check_usage_limits() to read current usage without row locks
- Add increment_usage_async() to update usage in background task
- Refactor job push logic to use optimistic validation
- Simplify job completion tracking with better error handling
This eliminates blocking row locks on the usage table during job creation,
significantly improving throughput and reducing contention.
Note: Requires running 'cargo sqlx prepare' with database access to update
the query cache in .sqlx/ directory.

* Update SQLx metadata
* refactor: optimize cloud usage checks with caching and conditional queries
- Add 60s cache for superadmin status checks to reduce DB load
- Skip unnecessary user usage query for premium workspaces
- Use existing team plan status cache (already implemented in windmill-common)
- Update check_usage_limits to accept check_user_usage parameter
- Add sqlx query cache for conditional user usage query
This optimization eliminates redundant database queries during job creation,
particularly for premium workspaces where user usage tracking is not needed.
