Task #191: Consolidate row-cell overlay icons into single kebab menu

The schedule's per-row affordances (delete, row color, merge cells)
used to render as three separate hover-revealed icon buttons stacked
inside the same narrow cell, which collided visually on iPad and
small screens. Replaced them with a single MoreVertical kebab trigger
that opens a Radix popover with three views (main / color / merge),
plus a "Back" affordance to return from sub-views to the main menu.

Implementation:
- New RowActionsMenu component (artifacts/tx-os/src/pages/executive-meetings.tsx)
  rendered once per row, anchored at the trailing-top of the first
  visible cell (matching the previous overlay anchor logic). Resets
  to "main" view on close.
- Old DeleteRowButton, RowColorPicker, and MergeMenu components removed.
- Existing testids preserved on the popover items so external tests
  still target em-delete-row-{id}, em-row-color-trigger, and
  em-merge-trigger-{id}. New testids added: em-row-actions-{id} for
  the kebab trigger, em-row-actions-back for the Back button.
- Locale keys added in ar.json/en.json: rowActions.label, rowActions.back.
- New imports: MoreVertical, ChevronLeft, ChevronRight (RTL-aware Back arrow).
- Merged-cell branch also uses RowActionsMenu so merge/unmerge stays
  reachable when the # column is hidden.

Tests:
- New regression spec: executive-meetings-row-actions-menu.spec.mjs
  exercises the full menu flow (open → color → back → main → merge → escape).
- Existing executive-meetings-edit-toggle.spec.mjs and
  executive-meetings-schedule-features.spec.mjs continue to pass —
  legacy testids remain absent in view mode and present inside the
  popover when opened in edit mode.

Pre-existing test failures (NOT caused by this change):
- "non-mutate user (executive_viewer)" spec fails because seeded user
  "ahmed" is missing from the dev DB (parallel task #131 drizzle work).
- TS errors in admin.tsx tracked by other tasks (api-client codegen
  out of sync).

Follow-up proposed:
- #192: show row color + merge previews inline in the main menu items.
