Advertise the jackpot that will actually be paid (B-65)

participant_count and jackpot_sats were computed over every round_participants
row, while the draw only picks from confirmed participants and the payout only
spends their sats. So the advertised jackpot could exceed the one paid out, and a
player whose bet was later abandoned appeared in the count and then vanished
again.

Counting only confirmed rows would have fixed the arithmetic and broken something
else: the player who just bet would see neither themselves nor their money for a
whole block. So this is the same confirmed/in-flight split the balance already
exposes (balance_sats vs pending_balance_sats): participant_count and
jackpot_sats are now the confirmed, authoritative figures, and
pending_participant_count/pending_jackpot_sats/has_pending_bets report what is in
flight — inclusive figures, not deltas, matching the balance pair's convention.

/'s round card shows the confirmed numbers big and the difference as an amber
"+N in attesa" suffix, reusing .balance-pending's colour for the same "not
settled yet" meaning. The two new spans render from server data through t(), so
they carry no data-i18n and onLanguageChange() repaints them from the last
response — the one-mechanism-per-element rule. Both strings are in all 7
languages.
