- Remove invalid feature flags (hybrid-search, filtered-search) that don't exist
- Replace with valid all-features flag for comprehensive testing
- Add PostgreSQL apt repository for older versions on Ubuntu 24.04
- Apply cargo fmt formatting to all crates
This fixes CI failures caused by:
- Feature flags that were planned but not implemented
- PostgreSQL 14 packages not available on Ubuntu 24.04 default repos
