fix: dynamic layout and pixel-accurate word-wrap in companion radio UI

Browse Source 
- All menu screens (Tools, Bot, Settings) now derive item height from
  display.getLineHeight() instead of hardcoded constants, preventing
  item overflow on 64px OLED displays
- ToolsScreen caps rendered items to screen height so Char Test is visible
- FullscreenMsgView word-wrap now uses display.getTextWidth() per candidate
  line instead of fixed char count, correctly handles variable-width and
  multi-byte UTF-8 glyphs; FS_CHARS_MAX increased 32→80
- CharTestScreen: fix v-arrow y-position; remove stale "→ blocks █" comments
