feat: improve logging and event filtering

- Add HTTP debug logging to TraccarHttpClient (URL, error body)
- Route HTTP client logs through app event log system
- Fix syncBufferedLocations to properly report partial failures
- Add DEBUG event type with separate filter chip
- Rename ALL filter to NORMAL, add VERBOSE (shows DEBUG, FILTERED, SPEED_CALC)
- Add color/icon for INFO, NETWORK_CHANGE, DEBUG, SPEED_CALC events
- Make log message text selectable
