Add per-profile TX routing and bridge filtering

Persist Companion TX preferences per contact and channel. Default repeater,
room, and sensor replies to both active TX profiles, with a reply-only force
option for an RX-only secondary profile. Track both reply copies before a
temporary-radio handoff and account for OTA copies under queue backpressure.

Add bridge/crossover filter modes and the third built-in wardriving filter,
plus compact filter CLI syntax, documentation, and CI coverage.

Fix quoted target names being interpreted as slot/key selectors, partial
recovery of invalid saved reply settings, filter suspension during tempradio2,
and unnecessary packet allocation while OTA traffic is throttled.

Validation: 1,477 native tests, 52 Python integration tests, 29 filter UI tests,
and five firmware builds covering ESP32, nRF52, and STM32 passed.
