admin_events: wire shared event-detail modal into the page

/admin/events previously rendered events as a flat table with no
detail view — admins had to copy an event ID and open the standalone
SFM webapp on port 8200 to see the chart, PDF, or sidecar metadata.

Adds:
- {% include 'partials/event_detail_modal.html' %} + script tag at
  the bottom of the page (mirrors the pattern in /sfm, /unit/{id},
  /projects/.../nrl/...).
- onclick on the table <tr> opens the modal via showEventDetail(id).
- event.stopPropagation() on the checkbox <td> so selection clicks
  don't also open the modal.
- Listener for the 'sfm-event-review-saved' CustomEvent fired by
  event-modal.js — reloads the table so any FT-flag changes made in
  the modal's review form land on the row without a full reload.

Also propagates the same listener pattern to the three other pages
that already include the modal (sfm.html, unit_detail.html,
vibration_location_detail.html) — they call their respective
loadEvents / loadUnitEvents / loadLocationEvents on the fire.  Keeps
the refresh-on-save UX consistent across every page that hosts the
modal.

Phase 1 of the SFM-into-Terra-View integration is now complete:
chart, PDF preview, .TXT download, review form, and per-unit + admin
event browsing are all native in Terra-View.  The standalone SFM
webapp on port 8200 remains as a diagnostic fallback but operators
no longer need to bounce to it for routine workflows.
