feat(deployments): mobile capture wizard + classify hopper + dashboard banner

UI for the pending-deployment workflow (commits 2 + 3 from the plan,
landed together since commit 1 already shipped the full backend).

New surfaces
- /deploy — mobile-first 3-step wizard.  Pick unit → take photo (uses
  <input capture="environment"> so it opens the phone camera) → add
  optional note + submit.  EXIF GPS auto-extracted on the server.
  Success page shows the captured coords + links to either "Deploy
  another" or "View pending hopper."  Whole flow is meant to take
  under 90 seconds on site.
- /tools/pending-deployments — the hopper.  Filter pills: Awaiting /
  Assigned / Cancelled.  Each card shows photo thumbnail, unit serial
  link, captured-at timestamp, coordinates, operator note, and
  status-appropriate actions.
- Classify modal on the hopper: two modes — "Assign to existing
  location" (project + location pickers, scoped to vibration_monitoring)
  or "Create new location" (with new-or-existing project, plus a
  "use captured coords" checkbox that writes the pending row's coords
  onto the new location).  Calls /pending/{id}/promote on submit.
- Cancel button uses prompt() for the optional reason → POSTs to
  /pending/{id}/cancel.

Backend additions
- GET /api/deployments/seismograph-picker — JSON list of non-retired
  seismograph units for the /deploy unit picker.  Annotates each unit
  with has_pending so the picker can flag units that already have a
  pending capture waiting.

Discovery
- New "Field Deploy" + "Pending Deployments" cards on /tools.
- Dashboard banner: auto-shows when there are awaiting captures,
  polled every 30s.  Hides when count drops to 0.  Click → /tools/
  pending-deployments.
