end storage transaction condition v15.0.1

Commits the storage transaction opened by start storage transaction and stores its result for a later retry of the same id.

Leave empty to end the transaction open in this flow. A bare id names a transaction this blueprint started; the qualified `bp::` reference from the start block names one started elsewhere : allowed only once that run's lease has lapsed.

Stored on the record and returned by a later start of the same id : the response a retried request should get.

Commits a storage transaction: marks it committed, stores `result` on the record (a later function_transaction_start of the same id answers already_committed with it), releases the opener's lease and keeps the journal for its retention. Without a wired transaction_id it ends the transaction currently open in this flow; after it, writes in this flow are ordinary writes again. Fails with TRANSACTION_NOT_FOUND when there is none, TRANSACTION_NOT_OPEN when it already ended, TRANSACTION_NOT_OWNED when it was opened by another run whose lease is still alive (ownership is the attempt token the start block put in this flow; a wired id carries none). A wired id names a transaction this blueprint started unless it is the qualified `bp:<blueprint>:<id>` reference. `transaction` carries the record (id, status, attempts, op_count, started, ended, result). In simulation nothing is written.

A typical wiring for end storage transaction: a function trigger starts the flow; the flow out pin feeds debug.
