Merge main into misc-fixes and address PR #202 review

Sync with upstream main and fix required items from review:

- updateTimelineLabels() now uses InterceptTime API (getTimezone/getIANA)
  instead of the stale selectedTimezone/TZ_MAP globals that were removed
  during the earlier InterceptTime refactor — fixes ReferenceError on TZ
  change and pass refresh.

- Remove profiles: [basic] from the intercept service in
  docker-compose.yml so bare `docker compose up -d` still starts the
  main service. Profile-gated services (intercept-history, adsb_db)
  stay as-is.
