adventure: let a player act from the web, not just read about it

The equip queue proved the reverse pipe works. This gives it verbs that
play the game: pull out of a run from the adventurer page, take today's
bout from the war room.

Its own table and its own poll, not more actions on equip_orders. Every
column of that table is equip vocabulary (item, slot, tier) and these
verbs act on the character rather than on something it is carrying.

Nothing in a request names an adventurer. The session maps to one
localpart and a localpart to one adventurer, so Pete resolves the
character itself and there is no id on the wire to forge.

The panel's copy is kept honest by the verdict: an applied action hides
the offer it has just spent, a refusal puts the button back. Watching it
run is what put that there, along with the strip's layout — gogobee
answers a bout with a whole sentence of damage, which the equip strip's
two-column row squeezed into a column and wrapped the verb.
