chore(theme-studio): remove dead code and clear a type warning

- ramp (app-core.js) and its test-ramp.mjs: superseded by regenColumn, no production caller.
- optList (app-core.js) and its tests: superseded by paletteOptionList.
- ITALIC in generate.py: computed, never read (ITALIC_MAP is the live one).
- a stray empty string in MU4E_FACES that .split() silently dropped.
- the dead #familytest alias in the columntest gate, which HASHES never listed.
- widen face_rows to Sequence[str], clearing the list-invariance warnings on the APPS calls.
