Implement configurable domain names for all copy link functionality

- Add PROD_SHARE_DOMAIN constant using existing AppString.PROD_PUSH_SERVER
- Update all 9 components/services to use configurable domain instead of hardcoded URLs
- Fix localhost issues in development mode for all sharing functionality
- Ensure all copy link buttons generate production URLs regardless of environment
- Add proper TypeScript imports and component properties for template access
- Maintain existing functionality while improving maintainability and consistency

Files updated:
- src/constants/app.ts (new constant)
- src/views/ClaimView.vue (claim + certificate links)
- src/views/ProjectViewView.vue (project links)
- src/views/ConfirmGiftView.vue (confirm gift links)
