Merge pull request 'map: remove stray clock, unstack incident rail, OSM tile fallback (#118)' (#122) from fix/118-map-overlays into main

collectionGroup alert_events (acknowledged, org_id, triggered_at desc) — the index the /watch Triggered Alerts tab and the site-wide useUnacknowledgedAlerts hook require. Still needs a manual deploy; no automation exists (#51).
