[Version-unspecific] Swap Queue /queue/swap endpoint
[Version-unspecific]
Intended to close #1469 (closed)
'[ADD] query to view txs in the swap queue'
At time of writing this has not been tested with a fullnode (my thanks to Bas1c for identifying the source of a problem!).
Nevertheless, OpenAPI editing may be appropriate.
In particular, I do not currently know whether a non-zero enum-related OrderType field will appear as a string
(e.g. "\u0001" as in Midgard-decoded bond events) or not,
nor what would be an appropriate OpenAPI description
if so.
