fix: correct inspector package name in Dockerfiles and add .dockerignore (#50)

* chore: remove inspect.sandboxagent.dev in favor of /ui/

* chore: add 404 page

* fix: correct inspector package name in Dockerfiles and add .dockerignore

- Change @anthropic-ai/sdk-inspector to @sandbox-agent/inspector in all Dockerfiles
- Add .dockerignore to exclude target/, node_modules/, etc from Docker context

The wrong package name caused pnpm install --filter to match nothing, so the
inspector frontend was never built, resulting in binaries without the /ui/ endpoint.

* chore: cargo fmt

* chore(release): update version to 0.1.4-rc.7
