fix: recipe quantities for conf+weight; move modal remembers location

- PHP (all 3 recipe endpoints): conf products with weight/volume package_unit
  (e.g., 300g/conf) now keep qty_number in sub-units (grams/ml) instead of
  converting to fractional conf. Post-normalisation block converts any AI-
  returned fractional conf values to grams automatically.
- JS submitRecipeUse: vacuum state now read from actual inventory item at the
  used location (_recipeUseContext.items), not from recipe ingredient data.
- JS showRecipeMoveModal: now uses _prefMoveLocCache preference system —
  after 2 consistent choices the modal is skipped automatically. 'Stay' button
  records the choice. Added _recipeMoveCancelStay() helper.
- JS confirmRecipeMove: records move choice via _recordMoveLocChoice();
  accepts optional forcedVacuum param for preference-triggered auto-moves.

Closes #108 (duplicate of #107 — data dir permissions)
