Housing Decor Guide

ADDED:
- Acquire "By Vendor" now lists the RECIPES each vendor sells, not just decor.
  Recipe rows read "Recipe: <decor name>" and dim until you've learned the recipe
  on any character; selecting one shows the vendor (with Navigate / Show on Map),
  the recipe's currency cost, and any renown requirement (e.g. Renown Rank 5 with
  The Singularity) beside the decor preview -- the same layout as a vendor-sold
  decor item. Recipe-only quartermasters (Lyrendal, Construct V'anore) now appear
  as vendors too. The "Crafted" source filter is renamed "Recipes".
- Vendor recipe sales are now stored in VendorDB (HDG_VendorDB[npc].recipes),
  migrated out of DecorDB's recipeSource so VendorDB is the single source of truth
  for what a vendor sells; the Trainers tab's Midnight Recipe Sources reads the
  same data. Recipe costs are structured currency (Artisan's Moxie + Voidlight
  Marl / Brimming Arcana / Remnant of Anguish) and render with icons.
- Crafted rows show their PROFESSION icon: the By-Vendor recipe rows and the
  Find-by-Item crafted decor rows now use the per-profession icon (Jewelcrafting,
  Inscription, etc.) like the Goblin tab, instead of a generic crafted icon. Under
  the Recipes filter, each vendor's (known/total) count includes its recipes.
- Quest completion is now tracked account-wide and BY CHARACTER (backported from
  HDGR). Acquire records which character completed each decor quest
  (HDG_DB.account.questCompletions, scanned when the tab opens) -- so a quest done
  on ANY character reads as complete everywhere (IsQuestFlaggedCompleted is
  per-character). Quest-source decor shows the completing character in the detail
  ("[Q] [Name] (check) (Vamoose)"), and the [Q]/[ACH] source tags dim until
  completed/earned then brighten -- completion reads at a glance. Owning the decor
  no longer auto-marks the quest/achievement gate complete: a vendor-sold item that
  also has a quest alt-source now reflects the real quest state, not your ownership.

CHANGED:
- Tidied the Stormarion Pinnacle recipe drop-source text -- dropped the
  "(end-of-dungeon)" parenthetical from the Trainers source line and the Acquire
  alt-source (Restful Bronze Bench, Voidstrider Saddlebag).

FIXED:
- Trainers tab "Map" button (Midnight recipe-source rows) now sources vendor
  coordinates from VendorDB by npcID instead of a second hand-baked copy in
  DecorDB -- the two had drifted (e.g. Eversong Woods vendors carried a stale
  mapID 2568; the live client uses 2395, so those waypoints landed on the wrong
  map). Baked coords removed from 25 in-VendorDB recipe sources; VendorDB is now
  the single source of truth. Recipe-only quartermasters absent from VendorDB
  (Lyrendal, Construct V'anore) keep their own coords as a fallback (Lyrendal
  nudged to 45.0/55.6; Construct V'anore filled in at 55.8/65.8). Fixed the same
  stale Eversong Woods mapID in the trainer-row waypoint table.
- Homely Wall Shelves (Inscription) recipe source corrected: it was mislabeled as
  vendor-sold by Lelorian for Artisan Scribe's Moxie (with a Map button), but the
  recipe is actually caught while fishing (Eversong Woods / Silvermoon City /
  Harandar / Zul'Aman / The Den). Retyped to a fishing drop source.
- Arrow-key (Up/Down) navigation in the Acquire item list no longer throws a Lua
  error -- ScrollToElementDataIndex was handed the no-interpolation flag in its
  numeric `offset` argument, so the scroll math ran on a boolean. Selection now
  scrolls into view cleanly.
