Enable uv cache in setup-uv

[mendral-app]

Summary

• Enable enable-cache: true on astral-sh/setup-uv@v4 in both lint and test jobs to cache UV_CACHE_DIR between runs
• On cache hit, uv python install and uv sync resolve from local cache instead of downloading ~70 MiB of packages per job

Diff: +4 lines (with: block added to each job)

First run will be a cache miss (cold start) — the cache is saved at the end. Subsequent runs on the same uv.lock will hit cache and skip all downloads.

Resolves insight: Enable uv caching to avoid re-downloading dependencies on every CI run
