Subject: [PATCH] feat: show item set name and bonuses in chat item link
 tooltips

Chat link tooltips (hover over item links in chat) were missing item set
information already shown in the inventory tooltip.  Now shows:
- Set name with equipped/total piece count (e.g. "Tier 9 (2/5)")
- Each set bonus with its piece-threshold, colored green when active
  and grey when inactive
- Falls back to "Set (id N)" when ItemSet.dbc is unavailable

Lazy-loads ItemSet.dbc on first hover; consistent with
InventoryScreen::renderItemTooltip formatting.
