fix: correct resources directory fallback path and eliminate code duplication in ssh_cache

- Fix fallback path from full path to "src" since full path is built
later
- Extract duplicate code from listCachedHosts and clearCache into
runCacheCommand helper
- Addresses feedback from @00-kat

src/cli/ssh_cache.zig
