Fix repayments that overcharged, and act on the first Frontier playtest

A debt repayment took its whole instalment even when less was owed: four
dollars owed at the store cost twenty. Content could not express "pay what is
owed", so an add effect's amount may now be read from state, with a cap. Five
repayments across both packs use it, and a conformance test holds every pack to
it. The turn record now says which options were hidden, so the analyser stops
counting doors nobody saw, and it reads only feedback logs.

From the same session: wages are labelled as wages, a clamped change says where
it stopped, two unreadable option labels are rewritten, the sale barn no longer
offers what the player already owns, Ward hints at what the promotion waits for,
and the office has five more events. DECISIONS #38-40.
