chore: Bump version to v2.18.0

Bluetooth enhancements (service data inspector, appearance codes, MAC
cluster tracking, behavioral flags, IRK badges, distance estimation),
ACARS SoapySDR multi-backend support, dump1090 stale process cleanup,
GPS error state, and proximity radar/signal card UI improvements.

It supports pager decoding, 433MHz sensors, ADS-B aircraft tracking, ACARS messaging, WiFi/Bluetooth scanning, satellite tracking, ISS SSTV decoding, AIS vessel tracking, weather satellite imagery (NOAA APT & Meteor LRPT), and Meshtastic mesh networking.

+Cross-compile on an x64 machine and push to a registry. This is much faster than building natively on an RPi.

+| Flag | Description |
+|------|-------------|
+| `--push` | Push to container registry |
+| `--load` | Load into local Docker (single platform only) |
