fix: address the final whole-branch review's findings

The branch review approved the slice with no blocking findings. These
are the substantive non-blocking ones.

N1, the one no per-task review could see: every seeded monster rolls
silverMin/silverMax = 0 (R7), so the victory screen showed "Silber +0"
after every fight in the shipped game. Three tasks were each correct in
isolation -- the mechanism stays, the values are zero, the field still
exists -- and the composite was wrong. Now conditional, with a test.
This does not contradict R16: R16 deleted the XP block because the
field ceased to exist, leaving nothing to hide. Silver still exists and
can be non-zero, so a conditional is the right tool.

N2: world.store.ts still said a combat "granted XP and silver". Same
false-fact-in-a-comment defect fixed in b5bcd50, one file over.

N4: resolveReputationRank threw a TypeError on negative input, since
findIndex returns -1 and REPUTATION_RANKS[-1] is undefined. Unreachable
today, but grantReputation is public and accepts any number.

N5/N6: grantReputation resolved factions without the enabled filter the
read path applies, so a disabled faction could accumulate invisible
reputation -- "disabled" was not actually a kill switch. The dense read
also had no ORDER BY, so the list could reorder between requests.

N8: design 13 requires silver stay 0 for every seeded monster; only two
of four were pinned. Re-adding silver to the others would have shipped
silently.

N9: spec 36's "a normal kill grants no Renown" had no test. It was
structurally guaranteed but unasserted -- now locked down against a
later slice wiring renown into combat.

N10: an impossible renown: 0 fixture, and RENOWN_MIN exported but never
used to clamp the floor.

API 268/268, web 230/230, API build zero errors.
