fix(docker): Add build tools for native modules and fix Debian package name

- Add python3 and build-essential to builder stage for bcrypt/sharp compilation
- Change libasound2 to libasound2t64 for Debian bookworm compatibility
- Copy pre-built node_modules from builder instead of re-running npm install
- Prune dev dependencies in builder for smaller production image
