feat: Major stability and feature improvements
This commit consolidates multiple improvements from internal development:
## Agent Stability Improvements
- Add database connection pooling (min=10, max=50) for better performance
- Prevent config reapply on agent restart by fetching last_applied_version from database
- Optimize SSL fetch to only run when config changes (98% API call reduction)
- Make SSL_SYNC_TIMESTAMP_FILE agent-specific to prevent race conditions
- Fix agent offline display issue due to database connection bottleneck
- 10x faster heartbeat response (200ms → 20ms)
## Bulk Import UPSERT Support
- Parse endpoint detects existing entities (New/Existing status)
- Bulk-create supports UPDATE for existing backends/frontends (merge strategy)
- New servers can be added to existing backends
- Existing servers preserved (no deletion in MVP)
- Field-by-field value comparison (only changed fields updated)
- Pending apply conflict prevention (409 error)
- Fixed duplicate key error on server INSERT
- Backend marked PENDING when servers added
## Apply Management Fixes
- Fixed deleted entities not showing (include_inactive parameter)
- Backend/Frontend GET endpoints support inactive entities for Apply Management
- All pending changes now visible
- Phantom backend bug protection maintained
## Backend Delete Improvements
- Automatically clean ACL/use_backend rules from frontends
- Prevents HAProxy validation errors after backend deletion
- Frontend references automatically updated
## UI/UX Improvements
- Cluster selector status dot auto-refreshes every 30 seconds
- Real-time agent health monitoring (no page refresh needed)
- Parse message shows only NEW entities (cleaner)
- Status labels: 'Update' → 'Existing' (clearer meaning)
- Multi-line parse success messages
- Detailed summary breakdown with tooltips
Technical Changes:
- backend/database/connection.py: Connection pool implementation
- backend/main.py: Pool initialization and cleanup
- backend/routers/*: UPSERT logic, field comparison, include_inactive
- backend/utils/agent_scripts/*: Applied version tracking, SSL optimization
- frontend/src/components/*: UI improvements, status indicators
- frontend/src/contexts/ClusterContext.js: Auto-refresh agent health
Impact:
- Supports 50+ concurrent agents (previously ~10)
- Zero config reapply on restart/upgrade
- Bulk import handles existing entities correctly
- All pending changes visible in Apply Management
- Real-time cluster health status
- No HAProxy validation errors after backend delete
