Updates: More Modal Modification (#8256)

Refactors modal dialog layouts for improved flexibility and consistency.

**Changes:**
- Add dedicated slot for left panel header title with dynamic
content/icons
- Consolidate side panel rendering within `BaseModalLayout`
- Remove redundant `PanelHeader` and `RightSidePanel` components
- Apply `select-none` to text elements to prevent accidental selection
