Add complete server-side internationalization support for non-JavaScript users

This commit extends the existing i18n system to fully support server-side translations
for users who have JavaScript disabled or are using the /table route directly.

Changes:
- Complete server-side Spanish (es-MX) translation support for /table route
- Language selector dropdown in table view with form-based locale switching
- URL parameter support (?locale=es-MX) for direct language selection
- Updated POST form handler to persist locale selection across submissions
- Proper locale detection and fallback for server-rendered pages
- Fixed language selector initialization timing in client-side JS
- Removed unused dependencies (canvas, sharp) to clean up package.json
- Added snowflake emoji to app name in both English and Spanish translations

The /table route now provides a complete non-JavaScript experience in both English
and Spanish, ensuring accessibility for all users regardless of their browser
capabilities or JavaScript preferences.
