Unlink Item

Detach an uploaded document (invoice/receipt) from a bank movement.

Removes the document plane's link only — the movement, the document and any GL booking stay. Use it when the movement was matched to the wrong document, or when its coding is held and you want to hand-code the movement instead (manual_code_entry refuses while a document match stands). link_id is the link_id of a row in get_bank_entry's links.items. The match status is recomputed, so the movement re-appears as unmatched and the matcher may offer it again.
