Replace the simple <ul> in the cascade-prompt panel inside the upcoming-
meeting alert with a 4-column table: row index, the meeting's
dailyNumber, title (truncate + title=), and "from → to". The new
`meetingNumbersById` map is built once in UpcomingMeetingAlert from
the already-loaded dayData and threaded through PostponeDialog into
both CascadePromptBlock call sites (postpone-minutes and reschedule).
Existing `cascade-followers-list` and `cascade-follower-<id>` testids
are preserved on the table/rows so prior selectors keep matching.
Adds 4 new i18n keys (cascadeColIndex/MeetingNumber/Title/Times) in
ar.json and en.json. The legacy cascadeListItem key is left in place
since it isn't worth a separate cleanup.
Extends the existing "Cascade prompt UI: Shift sends cascadeFollowing"
e2e test to assert the first row's index cell renders "1" and the
meeting-number cell renders the seeded follower's dailyNumber.
insertImminentMeeting now also returns dailyNumber so the assertion
can read it. tsc clean; targeted cascade specs pass (3/3).
