feature/i18n web config

[halibiram]

Summary

• Made NanoHTTP server pages (Addon and Repository Web Pages) i18n compatible.
• Added Turkish translations for web configuration pages.
• Escaped single quotes in JavaScript web UI translated strings to prevent syntax errors.
• Ensure that the app-selected locale is used for NanoHTTPD web config pages instead of the device's default language.

Why

The web configuration pages for addons and repositories were previously using hardcoded text and the device's default language. This PR ensures that the web pages respect the app's selected language instead, providing a consistent localized experience for users accessing the configuration pages via their browser.

Testing

• Manually verified that accessing the NanoHTTPD web configuration pages uses the correct translated strings based on the app's selected language.
• Checked that changing the app language dynamically updates the web page language without needing a server restart.
• Verified that single quotes in translations are properly escaped in the generated JavaScript.
