prosolis 5a8d21f780 adventure: fix concurrency + dup hazards in web equip path ...

Code review of the Ask-7 web equipment-management path surfaced three
correctness issues, all fixed here:

- applyEquipOrder ran the poll-goroutine equip mutations without the
  per-user advUserLock that every Matrix-side mutation (!give, !equip,
  arena, …) holds, so the lock gave no mutual exclusion against the web
  path. A concurrent !give of the item being equipped could duplicate it.
  Now takes advUserLock(owner) for the whole apply, matching the DM path.

- applyMasterworkEquip evicted the displaced occupant to the pack BEFORE
  the destructive slot write, so a fault left the piece both worn and in
  the pack — and the 30s equip poll retry re-evicted it every tick. Now
  removes the incoming row, writes the slot, then re-packs the occupant
  last as a best-effort step: once the slot no longer references it, the
  re-pack cannot duplicate, and a failure is logged not aborted on (the
  DM confirm handler's tolerance).

- PlayerDetail.Balance dropped omitempty: a real €0 balance is an
  informative fact, not an absent one, and omitting it left the web
  confirm dialog with no balance to show.
