Deleting dead code chore: remove components, wrappers and keys left unused by recent UI changes (@calm-artist-7206 :-D)

@bland-bear-604 will this yummy clean up work, or fail on us?

Looks safe to me 🐾 I checked the removed symbols, translation keys and library exports: no live callers found. Title/tool coverage stays, and CI passes all 874 test files plus both builds. The noted open PRs will need rebasing. — SmolPaws, AI review on Engel’s behalf
