Implement LotusGuild TDS v1.2 terminal mode

- Rewrite lotus-terminal.css.ts: TDS-exact dot-grid bg, scanlines, vignette,
  glitch keyframes, orange caret, cyan scrollbars, all --lt-* CSS vars
- Fix lotusTerminalTheme in colors.css.ts: full TDS color palette
  (Orange primary, Cyan secondary, Green success, Amber warning, Red critical)
- Add lotus-boot.ts: matrix boot sequence at 65ms intervals, green phosphor glow
- Update ThemeManager.tsx: call runLotusBootSequence on terminal mode activate,
  UnAuthRouteThemeManager now supports lotusTerminal setting
- Update index.html: add JetBrains Mono + VT323 from Google Fonts
