feat(ui-core,ui-lvgl): bot settings table in the Core, L2 bot screen

BotConfig (tabs, rows, the NodePrefs field behind each, reply placeholders)
moves into ui-core; ui-new's Tools > Bot renders it. L2: Home > Bot with
switches, list pickers, text popups with placeholder buttons, quiet hours.

 ### 5. Declarative settings schema
 
-`ui-core/SettingsSchema.h` holds three pages -- navigation (trail, live share, arrival alert, units), display & power (brightness, screen off, wake on message, battery shutdown, GPS power saving, time zone) and messages & contacts (DM resends, contact expiry, favourites first). An entry is a one-byte index by default, or a `values` table over a 1/2/4-byte field (seconds, millivolts, an hour offset, `{1, 0}` for a field stored inverted); side effects run through `UiCore` (`applyGpsInterval()`, `host()->applyDisplayPrefs()`). ui-lvgl renders each page; ui-new still uses its own screens. Radio settings are not schema rows (preset list, typed frequency, radio side effects): `ui-core/RadioControl.h` applies them (`applyParams`, `applyTxPower`, `applyApc`, presets = built-ins + user slots) for both ui-new's Settings > Radio and ui-lvgl's Radio screen. Channel management is `ui-core/ChannelControl.h` (`chanctl::`): add Public / Hashtag / Private (passphrase or 32-hex key), rename, delete, notifications / favourite / scope, and `onRemoved()` -- the cleanup of every channel-keyed pref, run by `UiCore::onChannelRemoved` whoever deleted the channel (this device or the app); contacts get the same through `UiCore::cleanupContactPrefs`. Favourites dial slots: `ui-core/Favourites.h`. Remote admin is `ui-core/AdminSession.h` (`UiCore::admin`): login with the saved password (forgotten on a wrong password or a silent timeout), CLI round trips with timeouts, the field table (`admin::`), typed values; results come out one at a time through `take()`. `UiCore` offers login answers and CLI replies to it first; only room logins it wasn't waiting for reach the frontend. ui-new's Tools > Admin and ui-lvgl's Admin screen are views over it.
