Delete applied candidate tag

Detach a single tag from a candidate. The {id} here is the applied-tag row id (returned by list/create), not the candidate id or the candidate_tag id; resolve it via GET /v3/applied_candidate_tags?candidate_ids=<candidate_id> when you only have the candidate. The tag itself remains in the organization's dictionary — use DELETE /v3/candidate_tags/{id} to retire the tag entirely.
