ui: the Data Connection event gains the date-time object; the "more" flag is precise

- The 0x1D event form now offers the Date-Time and Time zone object
  (TS 102 223 8.39): an optional select that includes the host clock's
  date-time, built by eventDateTimeTlv() as seven semi-octet BCD bytes in the
  TS 23.040 9.2.3.11 order (units high, tens low) with the time zone in
  quarters of an hour and its sign in bit 3 of the first semi-octet.
- The Cards list's empty-state colspan is 8 now (the table has had 8 columns
  since the keyset refactor, not 10).
- The expanded-registry "(first page only)" note marks only an unfulfilled
  6310: ramExpandedMore() keeps the promise set when the follow-up page was
  refused/failed or the page cap stopped the paging, and clears it when an
  accepted page ended the listing (a completed multi-page listing was
  annotated wrongly before).

Tests: eventDateTimeTlv (fixed dates, both timezone signs), the 0x1D build
with and without the date-time, and ramExpandedMore's cases.  Help EN/RU and
both AGENTS files; sw cache simple-v347.
