fix(core): stabilize item tooltip rendering

[mattiapearl]

Summary

• mount and hydrate lazy item-card tooltips while hidden before opening, with cancellation-safe request and trigger guards
• restore scaling indicators and optional numeric values through provider, tooltip, and card APIs
• render API-provided status metadata and elevated properties semantically without duplicate rows
• restore canonical soul-currency geometry and styling, refresh derived tooltip data when items change, and document the public controls

Validation

• npm run build (UI Core, React, and Vue)
• built-output Playwright smoke covering:
  • canonical price_currency.png, no filter, and stable baseline geometry
  • Retail Demo registration/computed family
  • API status icon/label, spirit scaling value, and elevated-row de-duplication
  • fully hydrated content at tooltipOpen while still hidden and in every sampled visible frame
  • immediate double-click and click-to-none cancellation without open events or leaked document listeners
• git diff --check

No card hover animation behavior is changed.
