Let the dealer find one hand in the log instead of scrolling the night

The hand log exists for one moment: somebody at the rail says they won a pot an hour
ago and wants it looked up. A night runs to sixty hands or more and the panel showed
five of them at a time, in a box fixed at 260px whether the dealer was on a phone or
a 27" screen with room for twenty. There was no way to ask for a hand — only to
scroll and read every row.

A filter box over the list now takes a name, an amount or a hand number. Matching is
loose on purpose: "fay" whatever case it's typed in, "190" for a $190 pot or a $190
payout, "$1,90" for the same typed badly, "#12" when the dealer knows the hand and
wants that exact one. Beside it, how much of the night is hidden — "8 of 60" — since
a filter matching one hand otherwise looks like a table that only played one.

The list also takes the room it has: clamp(200px, 42vh, 560px) rather than a flat
260, which is seven or eight rows instead of five on a desktop and no worse on a
phone.

Export stays the whole night, always. A CSV quietly missing the hands scrolled past
would be a record with holes in it and nothing on the file to say so — if a filter is
up when it's exported, the toast says how many went in.

Matching deliberately covers only what the row displays. Searching the full ledger as
well was the first attempt, so the hand that broke somebody could be found under the
loser's name — but the ledger holds everyone who put a chip in, and measured on a
seven-handed night where nobody folded, "Fay" returned 60 of 60. A filter that
searches text the panel doesn't show looks broken even when it's right.
