v2.14.0

Added

• An Export to Sheets dialog in the card footer, with a from-date and a
  Re-send days already marked as pushed option. Both were reachable only by
  calling export_all by hand before. The footer link is now on by default —
  an export button that ships switched off helps nobody.

Changed

• The footer link no longer fires an unconditional export behind a confirm
  dialog. It opens the range picker instead, defaulting to the first of the
  current month.

Fixed

• Documented the case the old button could not fix: a day is skipped when its
  fingerprint matches the last push, so rows lost on the Sheets side — a cleared
  tab, a deleted range, a push recorded but never delivered — stayed missing no
  matter how often the export was re-run. The force option ignores fingerprints.
  docs/sheets.md now also reads the sent/skipped/failed/total log line as a
  diagnosis.
