adventure: ask 7 — full equipment management from the web

Extends equip-from-the-web (ask 5, magic-only) to all five standard gear
slots. Owners get an Equipment panel on their own who page with:
  - Take off for worn masterwork/arena pieces (round-trippable to pack)
  - Upgrade to the next shop tier (spends euros, confirm-gated)
  - Repair a damaged slot (spends euros, confirm-gated)
The public Gear panel is hidden for the owner since this supersedes it.

Wire: equip_orders gains a tier column; new actions upgrade/repair; new
verdicts rejected_downgrade / rejected_insufficient_funds / rejected_max_tier.
PlayerDetail carries Slots (EquipSlotView x5) + Balance for the confirm
dialogs. handleEquipOrder resolves take-off/upgrade/repair from pd.Slots
server-side and rejects a client-forged tier (409), same as ask 5 trusts
only Pete's own record.

Verified: full suite green, headless render of the panel + confirm dialog
in both day and night phases. gogobee ships the poll-apply half separately;
Pete deploys first so its ingest accepts the new verdicts before gogobee
emits them.
