style(triage): redesign sidebar with divided sections + cleaner chips

- Replace the flat "eyebrow label + select" layout with three
  collapsible cards separated by hairline dividers, each with an
  icon, mixed-case title, inline summary, and chevron.
- Title-case all status/priority/summary text (no more lowercase
  "open" next to capitalized "Normal").
- Kill every sub-14px font; uppercase micro-labels were actively
  unreadable at 11px. Everything text-sm now, with dividers doing
  the separation instead of typography tricks.
- Chips: pill body is now a passive span; only the × button removes.
  No more "clicked the label and it vanished" accidents.
- Drop the redundant "No one assigned" row under the assignees
  picker — the picker's own "Add assignees" state is enough.
