feat(workspace): sliding sidebar in focus mode, calmer workspace bar, smoother journal

- focus mode: folders slide in from the left (button, title click, or the
  left edge on wide screens); picking a note keeps focus mode
- workspace bar: borderless live/shared/save pills in one style, divider
  before the note actions; footer without top line
- journal panel and calendar open with an animation, the view fades in
- paste and markdown import nest a list under the paragraph introducing it
