Adds configurable periodic 0-hop self-advert that includes GPS coordinates,
making the device's position visible in other nodes' Nearby Nodes screen.
Options: off / 1min / 2min / 5min / 10min / 30min / 1h.
Accessible via Tools → Auto-Advert. Timer runs in MyMesh::loop().

- Add NearbyScreen: GPS contact list with haversine distance sort,
type filter (ALL/Chat/Rpt/Room/Snsr), detail view with ping (RTT via
ACK poll), node scan via advert(), context menu
- Add DashboardConfigScreen: configure up to 3 data fields on the clock
page (Battery, Temp, Humidity, Pressure, GPS, Altitude, Lux, CO2,
Contacts); entered via long-press ENTER on clock page
- Rework HP_CLOCK layout: full-screen clock (size 2 at y=0), date at
y=19, separator at y=28, three data field rows at y=31/41/51;
hide node name/battery indicator on clock page
- Persist dashboard_fields[3] in NodePrefs and DataStore
- Add isAckPending() to MyMesh for NearbyScreen ping detection
- Wire NearbyScreen into ToolsScreen and UITask
- Reduce NearbyScreen entry buffer from MAX_CONTACTS(100) to 32,
saving ~3.3 KB RAM
- Switch haversine/bearing math from double to float (sinf/cosf/atan2f),
eliminating double libm and saving ~5-10 KB flash

Move three custom screens out of UITask.cpp into their own .h files
(RingtoneEditorScreen.h, BotScreen.h, ToolsScreen.h) and replace them
with three #include lines. UITask.cpp now only contains screens that
overlap with upstream (SplashScreen, SettingsScreen, QuickMsgScreen,
HomeScreen), making future upstream merges easier — custom screens live
in files that upstream will never touch.
