Improve asset caching and nullable API responses

Serve frontend assets from /assets with long-term caching while forcing no-cache for index.html to avoid stale hashed asset references. Update README with embedded images, docs link, license, support, and acknowledgments; bump docker image tag to hhftechnology/crowdsec-manager:v1.0.0. Remove now-unreferenced image files from images/. Normalize frontend API query handlers to return explicit nulls/defaults (using ?? null / ?? []), adjust related type annotations, and tweak a component prop to avoid runtime undefined values.
