Convert /admin/contact-edits list to live_table

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.
