0.8.1: UI cleanup pass on transactional screens

* Counting House screen:
  - 4-cell grid (was 5-col 5x2 wasted slots) with item icons centered
  - Inventory count badge bottom-right of each item cell
  - Detail pane: friendly display name, item id, on-hand count,
    list price, lifetime sold, effective fee, payout per unit
  - Sell 1/16/64 buttons grey out (and no-op) when you don't have
    enough of the selected item in inventory
* Bottom action row on all transactional screens: replaced "Refresh"
  with a single smart Back/Close button that returns to the Hub when
  opened from there. Fixes the overlap with sub-panel internal buttons
  that were caused by Refresh sitting at bottom-right.
* Panel heights reduced from (height - 30) to (height - 50) so the
  internal sell/action buttons don't clash with the screen-level
  action row.
* Same Back/Close pattern applied to TierUpgrade, Bounty, Plot, Journal.
* Removed "shop" alias from OpenScreenDispatcher — Counting House
  responds only to "counthouse" now. (No NPCs exist yet so this is safe.)
* Added "journal" as the canonical screen name for the Adventurer's
  Journal (replaces "questlog" — both keys still accepted in the
  command suggestion list for now).
