feat(fonts): Update fonts to Berkeley Mono + Lexend, simplify org-drill config

Font changes:
- Set Berkeley Mono + Lexend as default fonts
- Updated EBook preset to use Lexend
- Created FiraCode preset preserving old defaults
- Installed new fonts: Charis SIL, Bitstream Vera, Literata, Lexend

Org-drill changes:
- Removed fontaine-dependent font switching code
- Now uses org-drill's built-in display management
- Configured 24-point font, variable-pitch, hidden modeline
- Added comprehensive tests for display management (10 tests, all passing)

org-drill now loads from local ~/code/org-drill for development.
