docs(web): correct the victory-refresh comment about what combat grants

The comment claimed the server had granted "silver and renown" on a
combat win. It does not: grantVictoryRewards adds silver and item drops,
and nothing in apps/api/src/combat or apps/api/src/rewards touches
renown at all. Renown comes from milestones only.

Introduced when I committed Task 15's staged work after its agent was
cut off mid-step; caught by the task review.
