ci: Improve Docker build workflow and update dependencies

- Add release type detection to distinguish between version tags and edge builds
- Implement separate Docker build steps for release and edge builds with appropriate tags
- Add edge and SHA-based image tags for main branch builds
- Update nginx configuration to support Vietnamese (vi) language routing
- Simplify nginx location block to handle static files and fallback to index.html
- Remove javascript-obfuscator and ts-migrate from dependencies
- Update README with simplified self-hosting instructions using npx http-server
- Consolidate multiple server setup examples into single recommended approach
- Update build preview command to use npm run preview instead of npx serve
- Improve localization files for German, English, Vietnamese, and Chinese
- Update worker files and TypeScript logic files for improved functionality
- Enhance PDF tool pages with better structure and internationalization support
