The map_markers backend has accepted a `notes` column since PR #770 and
the popup display path was wired up to render it (commit 6328256), but
the placement UI never got an input. Result: notes are stored,
displayed when present, and impossible to actually enter via the UI.
Add a notes textarea below the name input in the placement popup,
thread the value through `addMarker` and `createMapMarker`, and trim +
null-coalesce on save. Notes display in the marker popup on click is
unchanged and now actually reachable.
- admin/inertia/lib/api.ts: extend createMapMarker request type with
optional notes
- admin/inertia/hooks/useMapMarkers.ts: addMarker accepts and forwards
notes (response already populated notes into local state, so no
display-side change needed)
- admin/inertia/components/maps/MapComponent.tsx: markerNotes state,
textarea after name input, threaded into handleSaveMarker
Edit-mode for existing markers (so users can backfill notes on
already-placed pins) is intentionally out of scope here - selected-marker
popup is still read-only. That's a follow-up PR if there's demand.
