perf: eliminate wasted API call, afterUpdate overhead, and sequential billing checks

- Remove unused projects.list() call fired on every console load (result was never consumed)
- Replace afterUpdate with reactive headerAlert subscription to avoid per-render overhead
- Parallelize billing checks with Promise.all instead of sequential awaits
- Fix database.subscribe() memory leak by wrapping in onMount for proper cleanup
