Align controls to same height with vertical separator

- Move analysis controls (period + button) to horizontal layout
- Add vertical separator (|) between database and analysis sections
- Align all controls at the same height for cleaner appearance
- Remove unnecessary nested vertical layouts
- Database controls on left, analysis controls on right
- Proper visual separation while maintaining compact layout
