refactor: App.js 1-list display + start/resume (no re-sort)

3 sites fixed to match shared 1-list model:
- line 1216 display: sortedParticipants = participants[] (no re-sort). GM
  list renders participants[] directly = turnOrderIds.
- startCombat inline: sort ALL participants by init (active+inactive),
  first active = current, persist participants[] reordered + turnOrderIds.
- resume inline: no re-sort on resume. turnOrderIds unchanged.

Display === rotation === turnOrderIds by construction (1-list invariant).
Build green.
