Unify sidebar fields: all editable fields use full-width clickable blocks

- Status and Severity now match CTI style (full-width button, hover bg, no chevron)
- Remove 'Change routing' hint text from CTI block
- Replace Assignee dropdown with clickable block that opens a modal picker with avatars
- Add Assignee modal consistent with Status/Severity modal pattern
