chore(gitignore): let Docker handle all compiled JavaScript assets

Remove exception for htmx.min.js so all compiled JavaScript in
web/static/ is ignored and generated during Docker build.

The Dockerfile already handles downloading HTMX via:
- npm postinstall script
- Downloads from unpkg.com during container build

This keeps the repository clean and lets the container build
process generate all static assets consistently.
