0.8.3: Adventurer's Journal becomes the "what's available + where to go" view

Rebuilt the Journal as a town-board view rather than just personal status.
Five sections, top to bottom:

1. Available Bounties — today's full pool of 5 with rewards + state
   markers (active/ready/cooldown). Header: "Visit the Bounty Officer
   at the Adventurer's Guild"
2. Plots For Sale — every plot with state (for sale / taken by X /
   yours). Header: "Visit the Plot Clerk at the Plot Office"
3. Exchange Rates — each wealth-token with list + your effective rate.
   Header: "Visit the Exchange Clerk at the Exchange"
4. Civic Tier — your current + next-tier cost. Header: "Visit the Civic
   Registrar at the Town Hall"
5. Your Status — active bounty progress bars, owned plot count, wealth
   summary

Each section header includes the NPC name + building so players know
which spawn building to walk to. The Journal itself is still read-only;
all transactions happen at the NPCs.

Content overflows the 360x220 screen, so the body uses a PanelScrollBar
(right edge) for vertical scrolling. Mouse wheel scrolls too.
