Wildlands UI Sprite System Update

• Unified inventory rendering so items, fragments, CapSouls, and blueprints all use the same sprite system instead of mixed emoji fallbacks.

• Fixed fragment inventory tab so fragment PNG sprites load correctly instead of emoji-only icons.

• Updated item rendering to resolve icons from recipe outputs → sprite keys → sprite cache.

• Blueprints now render using the sprite of the item they craft, instead of static emoji.

• Fixed CapSoul UI consistency so all CapSoul icons render from the sprite pipeline.

• Added sprite helpers (itemHtml, fragHtml, bpHtml) to standardize how inventory icons resolve.

• Patched crystal keepsake items so they render correctly and no longer reference invalid variables.

• Improved sprite fallback logic so missing sprites gracefully fall back to emoji instead of breaking UI.

• Expanded sprite preloading so commonly viewed inventory assets load faster.

• Inventory UI now consistently pulls icons from sprite_data.json + sprite cache instead of hardcoded emoji.

Result:
All inventory tabs now use a single sprite pipeline, making it easier to add new items, fragments, and blueprints without UI changes.
