fix: resolve all console errors and CSP violations

- Remove redundant chatInterface.initialize() call - already set up in constructor
- Fix ChatInterface to receive gameEngine instead of aiService
- Move inline script to external init-env.js to comply with CSP
- Properly structure all module dependencies and initialization
