release: v0.13.0 — SFM integration Phase 1

Phase 1 closes the read-only gap between Terra-View and the
standalone SFM webapp on port 8200.  Operators no longer need to
bounce between the two for routine event review.

Wraps up four commits shipped this iteration:
  db8d666  settings: add mic_unit_pref for event-report chart
  1d9fd00  event-modal: port 4-channel Chart.js waveform/histogram
           panels + docker-compose mount fix for SFM container
  4b2bb9a  event-modal: inline PDF preview + .TXT link + review form
  2905a32  admin_events: wire shared event-detail modal into the page

Highlights:
- Inline PDF preview via iframe (lazy-loaded; browser-native zoom)
- Chart.js 4-channel waveform/histogram in the modal
- Review form persisted to sidecar via PATCH
- /admin/events row click opens the modal (was port-8200-only)
- mic_unit_pref setting (dBL default, psi alternate; chart only)
- Cross-modal CustomEvent so host tables refresh on save

Phase 2 (device control: start/stop monitoring, push compliance,
erase) deferred pending SFM auth layer — see seismo-relay roadmap.
