Add uptime monitor features: fix history bars, lifetime stats, detail modal, custom services

- Fix 24-bar history rendering to always show 24 uniform segments with gray fill for missing hours
- Add lifetime uptime % and avg latency to status API
- Add clickable detail modal with expanded stats, large history bar, and service removal
- Add monitored_services DB table with CRUD API (GET/POST/DELETE)
- Monitor reads services from DB each interval, seeds defaults on first run
- Add inline form to add custom services to track
- Extend log retention from 7 days to 90 days for lifetime stats
