Adds a Delete Account row at the bottom of Settings, Account that calls
the new social.grain.unspecced.deleteAccount xrpc, signs the user out,
and dismisses the settings sheet. Uses a destructive alert so the user
can't trip the action accidentally. Error surface in the section footer.

iPad support required a 13" iPad screenshot for App Store submission,
which we don't have a design polished for v1. Drop iPad from the device
family so App Store Connect stops requiring the iPad screenshot.

Reads the new locationDisplay field from gallery and story views so the
UI renders one pre-formatted string instead of piecing together name and
address fields client-side. Falls back to location.name when an older
server hasn't shipped the field yet.

Also fixes two legacy issues that left county embedded in stored records:

- LocationServices.reverseGeocode no longer appends "county" to the
fallback name when Nominatim omits a POI name, matching the web's
geocoder output. New records won't have county in location.name.
- BlueskyPost.buildPostText handles legacy community.lexicon.location.
hthree records (no structured address) by using location.name as-is
instead of stripping after the first comma.

Adds NominatimResultTests covering the county exclusion and extends
BlueskyPostTests with legacy-record, county-embedded, and state-abbrev
cases.
