feat(emojiluna): add emoji name editing capability

- Remove disabled state from emoji name input field to enable editing
- Implement updateEmojiName service method with database persistence
- Add backend listener for emojiluna/updateEmojiName RPC endpoint
- Validate emoji name is not empty before saving
- Emit emoji-updated event after name change
- Add Chinese translation for name required validation message
- Update TypeScript declarations for new RPC endpoint

This allows users to edit emoji names directly in the emoji editor dialog.
