refactor: simplify severity to 3 levels (routine/priority/immediate)

Browse source 
- Replace 6-level system (info/advisory/watch/warning/critical/emergency)
  with 3-level military precedence (routine/priority/immediate)
- Every adapter remapped: NWS, NIFC, FIRMS, USGS, SWPC, avalanche,
  traffic, 511, mesh alerts
- is_critical flag removed — severity covers it
- Quiet hours: suppress routine only, priority+immediate always deliver
- Dashboard: blue/amber/red for routine/priority/immediate
- Fix hex node ID parsing in Mesh DM channel (!23261b70 format)
