Eight screens repeated the same if/else block to invert the row
background for selected items. Add DisplayDriver::drawSelectionRow that
sets LIGHT, optionally fills the rect, and leaves the colour as DARK
when sel (so the caller's text renders inverted). 61 lines removed
across SettingsScreen, KeyboardWidget (cells + special row), ToolsScreen,
DashboardConfigScreen, BotScreen, RingtoneEditorScreen (note slots +
menu), NearbyScreen, QuickMsgScreen (4 list views).
Card-style rows (QuickMsg hist, NearbyScreen discover, RingtoneEditor
notes display) keep their original drawRect/partial-fill outline for
unselected — they don't match the simple-invert pattern.

Add lineStep(), headerH(), listStart(), listVisible(), valCol() to
DisplayDriver so layout derives from getLineHeight() instead of fixed
OLED constants. Refactor all screens (SettingsScreen, NearbyScreen,
FullscreenMsgView, QuickMsgScreen, BotScreen, DashboardConfigScreen,
AutoAdvertScreen, RingtoneEditorScreen) and all HomeScreen pages plus
the lock screen and splash screen in UITask.cpp.
On OLED (lh=8) positions are unchanged; on landscape e-ink (lh=16) all
text and widgets now scale correctly to the 250×122 display.

BotScreen and DashboardConfigScreen were calling savePrefs() on every
exit regardless of whether any setting changed. Add _dirty flag set only
on actual value changes (toggle, channel select, keyboard confirm,
field cycle), reset on enter().

- 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
