feat: Full alert engine — 17 conditions, scaling cooldown, per-condition TUI toggles

Alert conditions across all 5 pillars:
  Infrastructure: offline, recovery, new router
  Power: battery 50/25/10%, 7-day trend, USB→battery, solar not charging
  Utilization: sustained >20% for 6h, packet flood >500/24h
  Coverage: infra single gateway, feeder offline, region blackout
  Scores: mesh <70, region <60

Scaling cooldown: immediate → 12h → 24h → 48h → stop
Recovery notifications when conditions resolve
Per-condition on/off toggles in TUI
Battery trend queries SQLite node_snapshots for 7-day history
