touch: beta_29 — clock floor for room-server replay guards, BLE repeats-heard, deep SD history, one-screen popups

- ClockFloorRTC on all boards: persisted monotonic send-timestamp floor (touchPrefs v32),
  garbage-set rejection, trusted-backstep cap; Join no-reply watchdog + server clock
  skew warning from the LOGIN_OK timestamp prefix (issue #89 follow-up)
- BLE repeats-heard: own-echo RX-log frames pass to BLE one-shot; the #46/#54
  congestion skip stays for everything else (issue #94)
- Mirror app-sent channel messages on-device (was Tanmatsu-only from birth)
- Chat delete: persist the ring purge; mesh-channel drop prefers the pinned slot
- Deep SD history (5000-msg ring) + date separators; chat-list rows restyled compact
- Popup unification: popupClose() + k_popup_registry drive dismiss/count/swipe-block
- Thread/channel sheet as one-screen 2-col grid (contact-sheet layout)
- Keypad nav: strip LVGL SCROLL_ON_FOCUS from collected widgets (About-page jump);
  update dot no longer focusable; verchk waits for an IP + retries with backoff
- Tanmatsu: FIRMWARE_RELEASE_TAG from git describe (drop the hand-bumped hardcode)
