Static-address loop-ins in autoloop are still experimental. Reject
loop_in_source=static-address at the RPC boundary unless loopd was started
with --experimental, and pass the same opt-in into the liquidity manager so
persisted params cannot bypass the gate after restart.
The existing static swap accounting remains wired through the manager; the
gate only controls accepting and planning new static-address autoloops.
Correct the duplicated article in the static openchannel
help text so the command summary reads cleanly. Refresh the
recorded help fixtures that surface that summary directly,
including the dedicated openchannel help output and the
parent static command listing.
