Reslot: handleInlineInitiative now sorts participants[] by init desc
(stable, tie-break original index) via sortParticipantsByInitiative.
Display + AdminView reflect new order after init edit. Not a blind
re-sort — only moved element changes position.
Gate: inline init field disabled when combat active + not paused.
Matches drag gating. DM must pause to edit initiative mid-combat.
Tests: InitiativeReslot.test.js (2). RED first (no reslot, Goblin stayed
at idx 1), green after impl (reslots to idx 0). Field gate test.
