feat(places): enrich list-imported places via the Places API (#886) (#1161)

* feat(places): enrich list-imported places via the Places API (#886)

Google/Naver list imports only carry a name and coordinates, so the places open
as bare pins — the Maps tab jumps to coordinates, with no photo, address or
open/closed. Add an opt-in "Enrich places via Google" toggle to the list-import
dialog, shown only when a Google Maps key is configured.

When enabled, after the (fast, unchanged) import the server runs a background
pass that re-resolves each place by name — biased to and validated against the
imported coordinates so a common-name search cannot overwrite the wrong place —
and fills the empty address/website/phone/photo columns plus the resolved
google_place_id, pushing each row over the live sync. Opening hours and the
proper Maps link then work on demand from the stored id.

Enrichment only fills empty fields, runs detached so a long list never blocks
the import, and no-ops when no key is configured.

* fix(places): use the ToggleSwitch component for the enrich toggle

Match the rest of the app — the import-enrichment opt-in used a raw checkbox;
swap it for the shared ToggleSwitch (text left, switch right) like the settings
toggles.
