Add chips to a seat without leaving the table

Somebody rebuying is the most common interruption in a cash game, and the only
way to record it was to open the seat editor and retype a stack from memory.

Press and hold a seat and there's now "Add chips…": quick amounts off the
table's starting stack — half a buy-in, a buy-in, two — with a keypad for the
times it isn't one of those. It's undoable like every other seat action, and it
records cash handed over as well as chips added, because those answer different
questions. The stack moves every hand; what a player has paid in only moves
when they buy.

The export gains bought in, chips now, and up/down, so settling up at the end of
the night is reading a row rather than reconstructing it.

Getting that last column right needed care. Chips in front of a player disagree
with the hand log for as long as a hand is open — and since blinds post the
instant the previous hand settles, that window is almost always. Counting what a
player already has in the current pot as still theirs makes the cash position
agree with the hand log at any moment, including across a rebuy.
