Remove a single operator secret field.
Deletes one key from the operator's encrypted credential blob without
touching the others — the field-level counterpart to
``forget_credentials``, which wipes the whole row. Use it to retire a
leftover after an SDK cutover (a Prefect key after Modal, or a stored
but untemplated orphan like ``anthropic_api_key``) without taking the
operator down for a full re-delivery.
Stored-but-untemplated fields are first-class: the delete is keyed on
what is vaulted, not on what the current template declares. Idempotent
— already-absent fields report ``removed: false`` without rewriting
the vault. RESTRICTED to the operator — requires the operator's proof
(a kind-27235 event or a proof grant); patron proofs are rejected.
A deletion is as destructive as a write.
