fix(docker): correct uv installation path

Fix uv symlink path from /root/.cargo/bin to /root/.local/bin.
The uv installer puts binaries in ~/.local/bin, not ~/.cargo/bin.

Changes:
- Update uv symlink source: /root/.local/bin/uv
- Add uvx symlink as well (installed alongside uv)

Fixes: /bin/sh: 1: uv: not found error during build
