fix: SettingsView TS errors + calendar month/year font

CI typecheck failed: JournalLocation interface requires `address: string`,
but Profile-tab Locations code created defaults like `{ label: 'Home' }`
without it. Symptoms were six TS2741 errors in SettingsView.vue.

Fix: include `address` in defaults and treat the user's place-name input
as the address field. Now homeQuery / workQuery sync to
locations.{home|work}.address — both at load time and on geocode.
loadJournalConfig now reads address (was reading label, which is fixed
to "Home"/"Work"); geocodeFor writes the typed query into address while
also setting lat/lon on success.

Calendar Month/Year title was actually rendering Fraunces, not Inter as
I'd claimed. FullCalendar renders .fc-toolbar-title as an <h2>, which
the global theme.css `h1, h2 { font-family: 'Fraunces' }` rule catches
before the parent .fc font-family inherit can do anything. At 1.1rem
it's below the doc's "Fraunces only at ≥18px" threshold, so explicit
Inter override on the deep selector.
