test: add offline fixture coverage for Kattis and USACO (#342)

## Problem

Kattis and USACO had zero offline test coverage — no fixtures, no
conftest
routers, and no entries in the test matrix. The `precision` field and
error
paths were also unverified across all platforms.

## Solution

Add HTML fixtures for both platforms and wire up `httpx.AsyncClient.get`
routers in `conftest.py` following the existing CSES/CodeChef pattern.
Extend the test matrix from 12 to 23 parametrized cases. Add a dedicated
test for the Kattis contest-vs-slug fallback path (verifying
`contest_url`
and `standings_url`), three parametrized metadata error cases, and a
targeted assertion that `extract_precision` returns a non-`None` float
for
problems with floating-point tolerance hints.

Closes #281.
