feat: add Enter key support for all text inputs

- Title input now commits on Enter/Tab key press
- Extra fields editing supports Enter/Tab commitment
- Keywords modal adds keywords on Enter key
- Extra fields modal saves on Enter when valid
- Maintains real-time updates while adding keyboard shortcuts
- Follows existing pattern from attachments/keywords components

This improves keyboard navigation and makes the UI more accessible for users who prefer keyboard
over mouse interaction.
