configWith let the day count and the Revenue floor disagree

minCombinedRevenue fell back to SOLO_CONFIG's constant — the floor for a
FIVE-Day game — whatever days said. configWith({ days: 1 }) asked a
one-Day game to clear 15, which a full five-Day game averages barely
half of; configWith({ days: 10 }) asked for that same 15. It derives
from the days it was given now.

Not a live fault: createLocalSession is the only caller and the page
always writes the floor itself, so no dealt game was ever wrong. Found
by a throwaway probe that passed only days — which is how the next
caller would reach for it. Unchanged at the default day count, since
SOLO_CONFIG's floor is this same formula at DEFAULT_DAYS.

Stays in the unshipped v0.7.9 per Jesse — no version bump for the next
several fixes. 873 tests pass, three new.

+`minCombinedRevenue` fell back to `SOLO_CONFIG`'s constant — the floor for a *five*-Day game —
+whatever `days` said. So `configWith({ days: 1 })` asked a one-Day game to clear **15**, a figure a
+full five-Day game averages barely half of, and `configWith({ days: 10 })` asked for the same 15 a
+five-Day game does. It derives from the days it was actually given now.

+Not a live fault: `createLocalSession` is the only caller, and the page always writes the floor
+itself, so no dealt game was ever wrong. It was found by a throwaway probe written to reproduce the
+extension bug above, which passed only `days` — which is exactly how the next caller would reach for
+it. At the default day count the answer is unchanged, since `SOLO_CONFIG`'s own floor is this same
+formula at `DEFAULT_DAYS`; the three new tests pin that as well as the derivation.
