fix(docker): fix self-hosting Docker build failures

Browse Source 
The self-hosting Docker Compose setup fails to build on a clean clone due to several issues:

1. Dockerfile.web did not copy .npmrc into the deps stage. The project uses shamefully-hoist=true, so without it pnpm produces a different node_modules layout and module resolution breaks.

2. The builder stage copied individual node_modules directories from the deps stage (COPY --from=deps). This breaks pnpm's symlink structure -- especially on Windows where symlinks resolve to host paths. Additionally, packages/tsconfig has zero dependencies so its node_modules never exists, causing a hard COPY failure. Fixed by copying the full workspace from deps and running an offline pnpm install to re-link after source overlay.

3. next.config.ts imports dotenv but it was not declared as a direct dependency in apps/web/package.json. It resolves locally as a hoisted transitive dep but fails the TypeScript type check during next build in Docker.

4. docker/entrypoint.sh gets CRLF line endings on Windows due to git autocrlf, which breaks the shebang (container looks for /bin/sh\r). Added .gitattributes to enforce LF for shell scripts and a sed strip in the Dockerfile as a safety net.
