feat(keyboard): add GUI key translation for M-S- bindings

Rename terminal-compat.el to keyboard-compat.el and add GUI support.

Problem: M-S-o and other Meta+Shift bindings didn't work in GUI mode.
GUI Emacs receives M-O (uppercase) but bindings use M-S-o syntax.
Terminal can't use M-O due to arrow key escape sequence conflicts.

Solution: Use key-translation-map in GUI mode to translate M-O -> M-S-o
for all 18 Meta+Shift keybindings. Terminal fixes unchanged.

Also fix two test issues:
- Remove expected-fail from expand-weekly test (timezone fix resolved it)
- Add helpful install messages to dependency-checking tests
