- Add ft4 to DEFAULT_MAP_SOURCE_FILTER (visible by default)
- Add ft4 hue to locatorThemeHues (peakHue + 30° offset from FT8)
- Propagate ft4 through locatorSourceLabel, locatorFilterColor,
locatorHueForEntry, isLocatorOverlay, applyMapFilter,
ensureDecodeLocatorMarker, pruneLocatorEntry, rebuildDecodeContactPaths,
clearMapMarkersByType, markerSearchText, navigateToMapLocator, and
the source items chip row
- ft8MapAddLocator now maps type="ft4" to markerType="ft4" so FT4
locators get their own distinct marker colour and filter chip
- ft4.js: pass "ft4" (not "ft8") to ft8MapAddLocator
