enhance(admin): allow regenerating access tokens for bot accounts (#40109)

Bot accounts cannot sign in, so admins manage their access tokens, but
the regenerate button was hidden for them. This adds an admin route to
regenerate a bot's token.

Token regeneration is now also recorded in the audit log.
