JakubandClaude Opus 5 919bf106b7 feat(companion): add device-originated message frames
Adds RESP_CODE_CONTACT_MSG_SENT_V3 (0x1E) and
RESP_CODE_CHANNEL_MSG_SENT_V3 (0x1F) so firmware that sends messages on
its own (bot auto-replies, on-device keyboard input) can mirror them into
the companion app's history, which today only ever sees inbound traffic
and messages the app itself sent. See #3225.

Both ride the existing offline-queue / MSG_WAITING / SYNC_NEXT_MESSAGE
pipe and reuse the RECV_V3 byte layout, with the pubkey field holding the
recipient instead of the sender and the SNR byte reserved. Requires
app_target_ver >= 3; there is no pre-V3 shape, so older apps are skipped.

Mainline never calls these -- nothing in companion_radio self-originates
messages -- so this is API surface for custom builds, and the linker
drops both functions when unused (identical flash usage before/after).
