Rewrite guest confirmation text; add discount and multi-day checkout

Copy button text now matches the exact guest-facing template
requested — "Ваше бронирование подтверждено!", Гость/Номер для
связи/Объект бронирования/Количество гостей/Дополнительные
пожелания/Скидка — dropping the internal-only fields (source, who
booked it) since this text gets pasted straight to the client, not
kept for internal records (those still show on the on-screen summary
card).

New checkOutDate column (nullable — null means same-day, the common
case) lets a booking span multiple days; the Google Calendar link and
copy text both show the date range when set. New discount column
(same shape as prepayment) feeds the new "Скидка" line.

Statistics page gains a money row for the selected month: total
booked, prepayments collected, amount still outstanding, and total
discount given.
