perf: cache blurred wallpaper to disk to avoid re-blur on startup

Browse Source 
First launch with blur blurs and saves to ~/.cache/moonlock/.
Subsequent starts load the cached PNG directly. Cache invalidates
when wallpaper path, size, mtime, or sigma changes.
Adds dirs crate for cache directory resolution.
