feat: T4 wave 4 - rules suggest, takeover, chains, autopilot A1-A3, suggestions page, varroa bands UI

- Automation rules propose suggestions instead of creating tasks;
  notify per rule config; corrected varroa measurements refresh or
  resolve their suggestion
- Inspection values can be taken over into the colony card
  (occupiedFrames 0-40, strength deprecated); warning counts use the
  same visibility rule as the notification list
- Biotech chains: swarm check after queen cells, queen acceptance
  check, split schedules (raise own, queen cell, queen)
- Season autopilot core with A1 inspection due, A2 varroa measurement,
  A3 recheck after treatment; colony sync and daily step
- Frontend: suggestions page with groups, bulk accept, undo, paging,
  focus management and permission gating
- Frontend: varroa traffic light from seasonal bands, sample size,
  one range request for the colony chart
- Notifications: mark-read answers 404 for rows the user may no
  longer see
