Phase 4 remainder: crafting screens, slider, config options

Game-file footprint unchanged: still one line in main.lua.

The slider turned out to be genuinely generic: modules/slider.lua is a factory,
so one wrapper on it narrates all four users -- craft, refine, trade and
ingame_wait (the wait-N-turns screen). Same leverage as the console.print and
inventoryCursorPopup patches.

The options screens do NOT share it, though: config_menu changes values through
config.increase/config.decrease, so it needed its own descriptor. It reports tab,
option name and value, and its focus key includes the value so left/right
re-announce even though the focused option has not moved.

states/_itemgrid.lua is now shared by inventory, craft, refine and trade, all of
which build a views/inventoryWindow. It stays silent while
confirmationWindowEnabled is set so the slider owns speech during quantity
selection instead of the two fighting.

testbed gains walkTo(), which navigates using the game's own pathfinder rather
than hardcoded direction sequences -- those drift as soon as anything moves the
player. The config test only adjusts a value when the focused option is
demonstrably safe, and puts it straight back.

The slider patch is applied and confirmed by the self-test but not exercised
live: ingame_wait is unreachable in the prologue because tutorial_bed overrides
bed's tryInteractFunction with an empty function by design, and the crafting
screens need an alchemy table and real items. Recorded as a NOTE rather than a
failing check, since it is a property of the game and not of the mod.

25/25 testbed checks, history unit tests passing.

+**The slider is genuinely generic** — `modules/slider.lua` is a *factory*

 ### Known gaps (next up)
-- **Phase 4 remainder**: `research`, `config_menu`, `keybindings_menu` have no
-  descriptors. `craft` / `refine` / `trade` are covered only by the
-  `inventoryCursorPopup` patch — so, like inventory was, they will be silent on
-  empty slots and say nothing about the quantity **slider** in the confirmation
-  window (`modules/slider.lua`, Left/Right adjusts, Shift for ×5).
+- **Phase 4 remainder**: `research` and `keybindings_menu` have no descriptors.
 - **Phase 5**: player status key (HP, statuses, current action), popup
   announcements (`popupStack.add`), damage alerts
   (`ingame.checkInterruptions`), mod settings.
