chore: simplify Dockerfile by removing unnecessary dependencies

Remove apt packages that aren't needed for running Next.js:
- Graphics libraries (libgl1, libegl) - not needed for web apps
- Build tools (build-essential, cmake) - app is pre-built
- ffmpeg - videos are served client-side, no server processing
- git, wget - files copied directly in build

The bun base image has everything needed to run the Next.js app.
