Fix formatting and clean up CellularScanner
Filter modem-fabricated cells and harden serving-cell parsing Verified against a Pixel 9 (Tensor) modem, which pads and corrupts CellInfo in several ways: - Drop unregistered WCDMA neighbors pinned at the reporting floor (Ec/No -24 or RSCP below demod sensitivity); the modem reports its whole configured neighbor set as unmeasured floor entries - Drop zero-identity placeholder cells (NR and WCDMA) emitted during NSA/RAT transitions: all-zero identity on a 0 Hz carrier with a clamped signal value - Skip unregistered cells whose measurement is older than the display TTL, so registry replays can't resurrect aged-out towers - Read the LTE serving cell's strength from SignalStrength when CellInfo omits RSRP, instead of dropping the serving tower - Remove a redundant UNAVAILABLE check in sanitizeCellId

Fix ktlint formatting in WifiCapabilities
Move the skeleton shimmer to the draw phase Reading the infinite transition's alpha during composition recomposed every warming card's scope at the animation rate. SkeletonBar now takes the State and reads it inside graphicsLayer, so the shimmer only invalidates the layer.
Harden Wi-Fi scanning and fix capability parsing Run the heartbeat and registration seed on the scan-callback executor so every apCache mutation is single-writer, which closes a lost-update race where the stale write-back could revert a concurrent scan's fresh data. Synchronize stop() with maybeRegister() in both the Wi-Fi and GNSS scanners so an in-flight registration can't complete after teardown, and guard the scan loop with the stopped flag. Parse security per capability bracket group and key the WPA2 badge on the group's PSK/EAP AKMs: the WPA2/RSN prefix alone also fronts WPA3-only (SAE) and OWE groups, which showed a phantom WPA2 label. Map 320 MHz channel width, move the 6 GHz band boundary to 5925 MHz with channel 2 at 5935, and clamp negative FTM distances from measurement noise.
Harden Bluetooth scanning and GATT inspection Require fine location in the scanner's permission check (BLUETOOTH_SCAN is declared without neverForLocation, so scans need it anyway), key the signal cache on advertisement content so payload rotations at steady RSSI refresh the details, and run all scheduled work on one serial lane so publishNow is single-writer. Match GATT read responses to the queued characteristic instance before disarming the read timeout: a late response for an already-timed-out read could strip the in-flight read's safety net and hang the inspection, and same-UUID characteristics now keep distinct values. Clear a pending write when a new inspection supersedes it, gate advertising support on the advertiser's existence rather than the multi-advertisement feature, decode Tx Power Level, and trim the NUL padding devices put in fixed-size string characteristics.
