Fix inconsistent note detail access in evidence_detail view

Previously, pressing Enter on a note in evidence_detail view would
open the notes modal (same as 'v' key), while in other views
(case_detail, tag_notes_list, ioc_notes_list) it would open the
note_detail view. This created confusing and inconsistent behavior.

Now Enter consistently opens note_detail view across all contexts:
- Enter: Opens note detail view (full note content)
- 'v': Opens notes modal (scrollable list of all notes)

This aligns the implementation with the help text which already
documented the correct behavior.
