The pending-edits list on the admin review page now sorts through
live_table. Columns for contact, submitted-by user, changed-fields
summary, and submitted timestamp are rendered via 2-arity custom
renderers so the Ecto-preloaded :contact and :user associations stay
accessible — live_table's data_provider path skips select_columns so
the full struct (with preloads) reaches the renderer.
The review drawer, diff table, approve/reject flow, and note textarea
all stay as-is; after approve/reject the page push_patches back to
its current path so live_table re-runs handle_params and the list
refreshes.
Pending count in the header now reads Radio.pending_edit_count/0
instead of length(@edits) since we no longer hold the full list in
socket state.
Registered users can suggest edits to any contact's core fields
(callsigns, grids, band, mode, timestamp). Edits enter an admin
approval queue with field-by-field diff view. On approve, changes
are applied and enrichment re-enqueued if grids/band changed.
Users receive email notification on approve or reject.
Also updates dependabot.yml for mix ecosystem.
