refactor(types): drop 127 unnecessary as any casts (#210)

Removed every `as any` in src/, then restored only the ones tsc still
needs: 163 → 36. 112 were in lotus-terminal.css.ts (`'… !important' as
any` etc. — vanilla-extract's style types accept these strings as-is),
so its file-wide eslint-disable goes too. The casts were type-only, so
emitted code and generated CSS are unchanged.

eslint warnings 49 → 46; the ratchet is tightened to match.
tsc clean; 1202 unit tests pass.
