docs(sales-summaries): show line-level before and after for each repair

The report asserted that the fixes work; it did not show what changed on the
page. Replaces the worked-examples section with actual summary lines pulled from
the restore, before and after, including debit and credit totals.

NGLK 2026-08-04 is the clearest case. The day already carried a $60.00 card
refund — the guest was given their money back, tip included — while the Tip line
still credited $482.94, because the reversal sits on an order with no tender and
get-tip only reached tips through tenders. Corrected to $422.94, matching the
refund to the cent, and the day closes from -60.00 to 0.00.

NTPT 2026-08-06 shows the other shape: $427.10 of service charge arrived inside
a $4,975.89 card tender, so it landed on the debit side with nothing crediting
it. Credits go 7,350.10 to 7,777.20 against unchanged debits of 7,777.20.

Adds the six largest repairs of each kind with their real Tip and Service
Charges figures, and NGNP 2026-06-25 where both fixes land on one day and pull
in opposite directions — 301.40 credited, 1.80 removed, 299.60 closed — which is
a useful check that the two are independent.
