chore(adminsite): remove the frontend test suite

Removes vitest, React Testing Library, the config, the setup file and all
eleven test files, plus the test scripts and dev dependencies. Done at the
user's direction; it matches the rest of the repo, which has no automated
tests in any language.

All eleven were observed passing before removal, and their assertions are
kept in the plan as acceptance criteria to check by hand rather than deleted
outright -- they are the clearest statement of what each component has to do.

Consequence worth stating: Task 16's manual pass is now the only verification
that exists for spec 4. Four behaviours it must cover carefully, because each
is easy to break invisibly: 404-not-403 scoping, the expired card naming what
still works, relink disabling at zero, and the blob fallback when a download
fails.
