Fix dispatch roster visibility follow-ups

[Clarion1631]

What changed

• Keeps a new drag visible while its persisted roster membership hydrates, while FINANCE stays excluded.
• Restores the dispatch-role regression set and pins missing membership fields as fail-closed.
• Applies the per-person dispatch switch to manager support, fixes the eight-column Team empty state, and uses selected-day dispatch copy.

Verification

• PASS: 28 targeted dispatch tests
• PASS: npm run typecheck
• PASS: scoped ESLint (22 pre-existing warnings, 0 errors)
• PARTIAL: production build compiles and typechecks, then cannot collect page data in this clean worktree because NEXTAUTH_SECRET is intentionally absent.

After merge: opt in Richard and CJ in Team, then verify the Dispatch roster.

1. ScheduleBoard.tsx:588 changes missing membership to fail-open. A legitimate drag originates from data.teamMembers, so the previous member?.showOnDispatch already preserved it. The new fallback only affects unknown users and fabricates an activated FIELD_CREW member. Keep unknown membership false and fix the actual hydration path by carrying explicit draft membership metadata. Add a behavioral test covering known opted-in, missing, opted-out, and FINANCE users.

2. The selected-day copy fix is incomplete. DispatchView.tsx:435, DispatchView.tsx:481, and DispatchJobCard.tsx:111 still say “today” while viewing another day. Make all visible and accessibility copy day-neutral or selected-day-aware.

3. dispatch-roster.test.ts:5 does not pin the regression set: it iterates the production constant itself, so deleting MANAGER or ADMIN from that constant still passes. Assert the exact expected tuple independently.
