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)
- src/components/HiddenDidDialog.vue (hidden DID links)
- src/views/UserProfileView.vue (profile links)
- src/views/InviteOneView.vue (invite links)
- src/views/ContactsView.vue (contact import links)
- src/views/OnboardMeetingSetupView.vue (meeting links)
- src/libs/endorserServer.ts (contact import confirm links)

Documentation added:
- docs/domain-configuration.md (comprehensive guide)
- README.md (quick reference section)

Testing: ✅ All linting errors resolved, only warnings remain
Performance: ✅ No performance impact, improves user experience
