Convert Vue components to use @Emit decorator instead of manual emits declarations

Replace manual emits declarations with proper @Emit decorator usage across components:
- ActivityListItem: Add @Emit methods for viewImage, loadClaim, confirmClaim
- ContactInputForm: Convert handleQRScan to use @Emit("qr-scan")
- ContactBulkActions: Add @Emit methods for toggle-all-selection, copy-selected
- ContactListHeader: Add @Emit methods for all 5 emitted events
- MembersList: Add @Emit("error") method for error handling
- LargeIdenticonModal: Add @Emit("close") method
- ContactListItem: Add @Emit methods for all 4 emitted events

Update all templates to call emit methods instead of direct $emit calls.
Fix TypeScript type issues with optional parameters.
Resolves Vue warning about undeclared emitted events.

Follows vue-facing-decorator best practices and improves code consistency.
