feat: add cache busting script for JS imports during Docker build

Browse source 
- Introduced a new script to append version query parameters to JS imports, ensuring proper cache busting in production.
- Updated Dockerfile to copy and execute the cache busting script during the build process.

This enhancement simplifies cache management for JavaScript files in production environments.

# Simple cache busting script - adds version query params to all JS imports
# Only runs during Docker build, not during local development
# This keeps development simple (no tools needed) while ensuring production cache busting
