Track strongest signal per detection to capture GPS at closest approach
to surveillance devices, rather than only first-seen position. All exports
(JSON, KML, CSV, SPIFFS, dashboard, radar) updated to use best GPS.
Also adds battery ADC monitoring framework (disabled by default until
voltage divider hardware is wired) and uptime display in stats bar.

- Proximity radar with canvas-based RSSI rings, sweep animation,
and detection blips positioned by haversine bearing (GPS) or
MAC hash (fallback)
- Three switchable themes (Purple/Tactical/Ithildin) with
localStorage persistence
- Subtle grid overlay, card gradients, glow effects, pulsing
status indicator, detection-type left-border colors
- RSSI bar chart for at-a-glance signal strength comparison
- Randomized taglines on load
- Added device_lat/device_lon to /api/stats for bearing calc
- All CSS colors via custom properties for theme support

Added Adafruit_NeoPixel.h and ESPAsyncWebServer.h includes that were
implicitly resolved in OUI Spy but needed explicitly in standalone build.
Added forward declarations for fyGPSIsFresh() and fyAddDetection() so the
WiFi promiscuous callback can reference them before their definitions.

ESP32 promiscuous callback parses 802.11 management frames (probe requests
+ beacons), extracts source MAC OUI, and checks against wifi_mac_prefixes[]
table. Deferred alert pattern avoids calling delay()/tone() from WiFi task.
AP dashboard continues serving at 192.168.4.1 while scanning.

OUI Spy Unified Blue is by colonelpanichacks, not lukeswitz.
Full lineage: wgreenberg (flock-you BLE research) ->
colonelpanichacks (OUI Spy unified multi-mode firmware) -> Dantir.
