Refactor ClaimView.vue: remove inline template logic, improve types, and centralize logic

- Move all complex template logic to computed properties and methods
- Replace all `as any` usages with proper TypeScript types (OfferClaim, GiveActionClaim)
- Add computed property for claim image, removing inline image access
- Route all logging through PlatformServiceMixin
- Ensure all icon-only buttons have aria-labels for accessibility
- Remove unused imports and direct logger usage
- Lint clean: no warnings or errors remain
