Implement end-to-end support for typed screenshots and priority rendering in monitoring.
Added
- Accept and forward screenshot_type from MQTT screenshot/dashboard payloads
(periodic, event_start, event_stop)
- Extend screenshot upload handling to persist typed screenshots and metadata
- Add dedicated priority screenshot serving endpoint with fallback behavior
- Extend monitoring overview with priority screenshot fields and summary count
- Add configurable PRIORITY_SCREENSHOT_TTL_SECONDS window for active priority state
Fixed
- Ensure screenshot cache-busting updates reliably via screenshot hash updates
- Preserve normal periodic screenshot flow while introducing event_start/event_stop priority path
Improved
- Monitoring dashboard now displays screenshot type badges
- Adaptive polling: faster refresh while priority screenshots are active
- Priority screenshot presentation is surfaced immediately to operators
Docs
- Update README and copilot-instructions to match new screenshot_type behavior,
priority endpoint, TTL config, monitoring fields, and retention model
- Remove redundant/duplicate documentation blocks and improve troubleshooting section clarity
