Housing Decor Guide

* Fix: PowerCrafting PruneProfessionsDB Category A was matching housing
  decor recipes against HDG_ProfessionsDB by spellID, but ProfessionsDB
  is keyed by itemID. Match never succeeded, so EVERY housing decor
  recipe was being pruned out of the in-memory ProfessionsDB on load,
  collapsing the sub-recipe DAG (no crafted reagent chains, no "what
  produces this intermediate" lookups). Materials list and crafting
  readiness widgets that depend on the DAG now resolve correctly.

* Fix: PowerCrafting CanPlayerCraft always returned false. itemIDIndex
  stores the ProfessionsDB key (= itemID), but the function passed it
  straight to PlayerKnowsRecipeBySpellID — itemIDs and spell IDs occupy
  different numeric ranges. Now dereferences the entry and passes the
  real entry.recipeID. Restores correct results for any caller asking
  "can the player make this sub-component?"

* Fix: Acquire tab craftableByItem cache was storing the HDG_DecorDB
  table key (legacy decor record id) instead of the actual
  recipe.spellID, mirroring the same loop-variable shadowing bug as the
  Decor Preview tab. Symptom was latent (downstream uses are boolean
  ~= nil checks) but the value is now correct for any future consumer.

* Fix: Decor Preview craftable column was showing recipes you actually know
  as "no one knows it" (faint outline) for older expansions.
  decorToRecipeCache was storing the legacy decor record id from the
  HDG_DecorDB table key instead of the real recipe spellID field, so
  PlayerKnowsRecipeBySpellID was being queried with the wrong number and
  the persisted-cache lookup never matched. Recipes in your knownRecipes
  cache (Alts tab counts) now light up gold correctly across all
  expansions. Same fix applied to two other call sites using the same
  misleading loop variable.

* Fix: PlayerKnowsRecipeBySpellID now reads the persisted profession
  cache first (HDG_DB.characters[me].professions[*].knownRecipes) and
  falls back to live C_SpellBook.IsSpellKnown only as a pre-scan
  catch-net. The live API only sees recipes for the currently-slotted
  expansion profession, so older-expansion recipes returned false even
  when learned. The cache scan (run when the profession window opens)
  records every learned recipe across all expansions, so the cache is
  the authoritative answer once a scan has happened.

* New: Current house name shown right-aligned on the GRAND CURATOR
  title line of the Decorator Profile. Reads the active neighborhood
  from the MultiHouse cache (HDG_DB.account.houses) and tints the
  label by faction (Alliance blue / Horde red). Updates each refresh.

* Fix: GetCharactersWhoKnowRecipe had the same flaw as the
  PlayerKnowsRecipeBySpellID issue above — the CURRENT character was
  checked via live C_SpellBook.IsSpellKnown only, while alts correctly
  used the persisted cache. Result: "Recipe known by:" tooltips would
  list only your alts and omit YOU on older-expansion recipes you
  actually know. Now cache-first; live API is the pre-scan fallback.

* Fix: Find Lumber detection on the Alts tab top-right used the
  deprecated IsPlayerSpell global, which returns nil on retail.
  Replaced with the verified C_SpellBook.IsSpellKnown(1256697). The
  "Find Lumber known" indicator should now actually light up for
  characters that have learned it.

* Polish: Decor Preview "Craftable" column unified to a single icon
  family. The old mix of bright gold star / dim grey star / dim
  checkmark / bright red X was visually inverted from utility — the
  loudest icon (Red X for "not craftable") was the least actionable.
  Now: bright gold star = you know it, silver dim star = an alt knows
  it, faint outline star = recipe exists but no one knows it, empty
  cell = not a recipe (vendor / drop / event). Source category for
  non-craftables stays in the tooltip and Acquire tab. The check icon
  was also dropped — a check-mark for "recipe exists but you don't
  know it" was counter-intuitive (checks usually mean done). Tooltip
  legend updated to match.

* New: "Reset Config" button on the Appearance card — wipes
  HDG_DB.config and reloads from defaults via a confirm popup. Recovers
  from stale appearance/behaviour settings that can't be reached via
  normal UI controls (e.g. fontScale stuck non-zero from old builds, or
  legacy keys left behind by the HDG_Settings backward-compat proxy
  that cause text to render visibly wider than expected and overflow
  column widths). Shopping lists, characters, lumber map, custom
  styles, and House tab layout are preserved. Popup explains a /reload
  is sufficient in most cases; full relog only if anything looks off
  afterwards.
