Add read-only note view screen

Mårten Åsberg committed on 2026-08-01 at 15:54

Tapping a note in the list now opens its full raw markdown content
(monospace, unrendered, selectable), showing the cached preview
instantly while the full content loads over Graph. Editing and note
creation remain out of scope for this milestone.
