Lifted the per-row missing-time drag block (originally #492). Meetings without a (startTime, endTime) tuple are a normal state and now rotate freely alongside timed rows. Server (artifacts/api-server/src/routes/executive-meetings.ts): - Dropped the `no_time_window` early-return guard in /api/executive-meetings/rotate-content. - Sort + slot construction now tolerate null start times (NULLS LAST, tie-break by id) so a null tuple rotates as a real slot. - All other safeguards (cancelled_in_rotate, optimistic lock, renumberDayByStartTime, audit logging) remain intact. Client (artifacts/tx-os/src/pages/executive-meetings.tsx): - Removed missingTimeCount / dayRotatable memos, the dayRotatable prop wiring, dragBlockedByMissingTime + effectiveDragEnabled composition, the row's data-drag-blocked / native title / cursor-not-allowed-opacity-80 / aria-disabled overrides, the entire DragBlockedTooltipButton component + its render site, and the no_time_window errorToast branch in rotateContent. Pruned now-dead Tooltip + AlertTriangle imports. i18n: removed the `executiveMeetings.rotate.needsTimeWindow` block (tooltip + errorToast) from en.json and ar.json. Tests: deleted `executive-meetings-rotate-needs-time-window.spec.mjs` and added `executive-meetings-rotate-allows-missing-times.spec.mjs`, which inserts 3 meetings (one with null times), verifies no drag-blocked warning button / aria-disabled, drags the top row to the bottom slot, asserts the rotate-content POST succeeds, and confirms exactly one row still has a null tuple after rotation. Verified: row-drag, row-quick-actions, and the new spec all pass (8/8). Architect code review PASSED.
