Description

Adds city-name echo to the location search field in all three places and fixes a couple of related issues found while testing:

• Theme & Gamma auto-location now persist the selected city name in a new nightModeLocationName session property and prefill the search field with it; manually editing coordinates clears the name again.
• Weather search gets the same echo via the existing weatherLocation, and no longer silently loses it when the settings tab initializes or fills coordinates from a search result.
• Manual coordinate fields in Theme & Gamma now use the same full-width layout as the weather page (aligned insets, matching title weight).
• DankLocationSearch (via the submodule bump) now shows a selected-state check icon after picking a result instead of a misleading error icon, and supports the currentLocation echo.

Have tested on hardware with https://github.com/Curious-r/nix-config/tree/test/dms-location-search-echo

• Search → select a city: lat/lon auto-fill and the day/night switch reacts in both Theme & Colors and Gamma Control.
• Echo: after selection, reopening settings or switching tabs prefills the search field with the city name; manually editing lat/lon clears it back to the placeholder.
• Cross-tab: coordinates and the echoed name stay in sync in both directions (Gamma ⇄ Theme), including after manual edits.
• Icon: focusing the search field after a selection shows the check icon rather than the red error icon.
• Layout: the unified manual-coordinates form renders correctly in both tabs.
