feat: migrate all clipboard operations from useClipboard to ClipboardService

- Replace useClipboard with platform-agnostic ClipboardService across 13 files
- Add proper error handling with user notifications for all clipboard operations
- Fix naming conflicts between method names and imported function names
- Ensure consistent async/await patterns throughout the codebase
- Add notification system to HelpView.vue for user feedback on clipboard errors
- Remove unnecessary wrapper methods for cleaner code

Files migrated:
- View components: UserProfileView, QuickActionBvcEndView, ProjectViewView,
  InviteOneView, SeedBackupView, HelpView, AccountViewView, DatabaseMigration,
  ConfirmGiftView, ClaimView, OnboardMeetingSetupView
- Utility functions: libs/util.ts (doCopyTwoSecRedo)
- Components: HiddenDidDialog

Naming conflicts resolved:
- DatabaseMigration: copyToClipboard() → copyExportedDataToClipboard()
- ShareMyContactInfoView: copyToClipboard() → copyContactMessageToClipboard() → removed
- HiddenDidDialog: copyToClipboard() → copyTextToClipboard()
- ClaimView: copyToClipboard() → copyTextToClipboard()
- ConfirmGiftView: copyToClipboard() → copyTextToClipboard()

This migration ensures reliable clipboard functionality across iOS, Android,
and web platforms with proper error handling and user feedback.

Closes: Platform-specific clipboard issues on mobile devices
