- NodePrefs: add buzzer_volume field (0=min..4=max, default 4)
- DataStore: persist buzzer_volume at end of prefs file (backward-compat)
- buzzer: setVolume()/getVolume(); applyVolume() sets PWM duty cycle via
analogWrite() after each rtttl::play() call to control output amplitude
- Settings UI: new BzrVol bar item in Sound section (left/right to adjust)
- UITask: apply saved volume on startup alongside brightness

- DataStore: persist custom_msgs, ch_notif_override/muted, dm_show_all,
room_fav_only — none were being saved/loaded, all settings lost on reboot.
Load uses file.available() guard for backward compat with old saves.
- QuickMsgScreen reset(): clear _ctx_open/_ctx_dirty/_ctx_sel so context
menu state is clean when re-entering the messaging screen.
- Remove unused _ctx_ch_idx field (code always uses _channel_indices[_channel_sel]).
- _room_unread: cap at _msgcount before incrementing to prevent badge
going negative (getMsgCount() - getRoomUnreadCount()).

Save last known unix timestamp to /rtc_save on shutdown and restore it
on startup, so the clock shows correct time immediately after restart
without waiting for GPS fix.

Filter auto-add of new contacts by hop count (issues #1533, #1546).
Setting is configurable from the companion app via extended
CMD_SET/GET_AUTOADD_CONFIG protocol (0 = no limit, 1-63 = max hops).

* companion: new field in CMD_SET_OTHER_PARAMS, path_hash_mode
* companion: CMD_SEND_SELF_ADVERT, cmd_frame[1] now holds the path hash size (0 = zero hop, 1..3 = flood path hash size)
Add GPS configuration to NodePrefs structure and persist the GPS
enabled state when toggled via UI. This ensures GPS settings are
retained across device restarts.
