Make the pot button offer a pot-sized raise

The raise pad worked its quick amounts out as "the current bet plus the pot as it
stands". That leaves out the raiser's own call, which is in the pot before the raise
is measured off it, so every amount came out short. Measured pre-flop at 1/2:

    offered:  Min $4    ½ pot $4    Pot $5
    correct:  Min $4    ½ pot $4.50  Pot $7

A pot raise there is: call the $2, which makes the pot $5, then raise $5. And the
half-pot was so short it clamped up to the minimum and sat next to the Min button
showing the same $4 twice, which is how it went unnoticed — it looked like a table
where those two happened to coincide.

"Pot" is not a suggestion. It is a definite number players say out loud, and a dealer
tapping the button that claims to be it should be recording what was actually said.

The rule moves into Betting.potRaiseTo, next to the other rules and testable on its
own, rather than living as arithmetic inside a DOM renderer:

    raise to = the current bet + (pot + what they owe) × fraction

Facing no bet it comes out as a plain pot-sized bet, because both the bet and the
amount owed are zero. Facing a bet it comes out as three times the bet plus the dead
money, which is the shape a player checks it against.
