Static screens (SettingsScreen, BotScreen, FullscreenMsgView, message
list, contact picker) were re-rendering every 300ms with no visible
benefit. New messages still trigger immediate refresh via newMsg() →
_next_refresh=100, so responsiveness is unchanged. Reduces unnecessary
SPI transfers and CPU wakeups ~6x on idle static screens.

Text lines fill the full display width, causing the last chars to bleed
into the scroll arrow area. Draw a DARK fillRect behind each arrow before
rendering it, so the arrow appears on a clean black background without
truncating the text width.

Raw UTF-8 message body was passed directly to display.print(), rendering
Polish and other accented chars as garbage on the Adafruit font.
Transliterating before wrapLines also fixes byte-count wrapping for
multi-byte UTF-8 characters.

- Add getCharWidth()/getLineHeight() virtual methods to DisplayDriver so
all layout math adapts to whatever font is active
- Fix Lemon font baseline offset from +8 to +6 (cap height, not FONT_ASCENT)
- Add LemonIcons.h with Private Use Area glyph table; U+E03B mute icon
rendered via drawLemonChar icon lookup
- FullscreenMsgView: compute wrap width and visible lines dynamically from
display font metrics instead of hardcoded constants
- SettingsScreen and MessagesScreen: replace hardcoded ITEM_H/VISIBLE with
members computed at render() time from getLineHeight()

- Swap left/right navigation in fullscreen view: left=newer, right=older
- Update arrow indicators to match new direction

Shared struct handles rendering and input for both DM and channel fullscreen
views, replacing ~80 lines of duplicated inline code. Fixes navigation arrow
indicators being swapped in channel fullscreen.
