Merge upstream companion-v1.17.1 into power-saving

Pulls in real fixes: scoped-reply routing, RX boosted-gain restored
correctly after AGC reset, T-Echo Lite/Card SPI pin corrections
(unused pins now map to NRFX_SPIM_PIN_NOT_USED via 0 instead of -1)
and TCXO voltage fix, Heltec T096/T1 and MeshPocket pin fixes,
T-beam Supreme S3 display fix, LR2021 preamble/IRQ timeout handling.

None of the touched variants overlap with our active Heltec V3/V4,
Cardputer ADV, GAT562, or WioTracker builds.
