chore(types): replace any with i18next TFunction in AdminAuditLog

translateAction took 't: any' with an eslint-disable on top — the only
explicit 'any' annotation in the entire src/ tree. Inline TFunction from
i18next; same call sites, full type safety on the i18n lookup. Now zero
'any' annotations in src/.
