Make note navigation consistent across case_detail and evidence_detail

Both views now support dual navigation options:
- Enter: Opens note_detail view (single note focus)
- 'v': Opens notes modal with selected note highlighted

Previously, case_detail would open the notes modal from the beginning
even when a case note was selected. Now it intelligently jumps to the
selected case note, matching the behavior in evidence_detail view.

This provides a consistent, predictable user experience across both
views where notes can be selected and viewed.
