fix(contests): prime correct count cache key in useUserRemixContests

The profile Contests tab primed `getRemixesQueryKey({ pageSize: 0,
isContestEntry: true })`, but `ContestCard` reads from
`useRemixesCount`, which is keyed by `getRemixesCountQueryKey`. The
mismatch meant primed counts were never read — every card fell through
to its own `/tracks/{id}/remixes?limit=0` request, with the badge
showing "0 ENTRIES" until that fetch resolved.

This mirrors the fix already applied to `useAllRemixContests` in
#14271 ("normalize lineup shape"). The companion hook was missed at
the time.
