Kristjan ESPERANTO 5c1cc476f3 [newsfeed] refactor: migrate to centralized HTTPFetcher (#4023)
This migrates the Newsfeed module to use the centralized HTTPFetcher
class (introduced in #4016), following the same pattern as the Calendar
module.

This continues the refactoring effort to centralize HTTP error handling
across all modules.

## Changes

**NewsfeedFetcher:**
- Refactored from function constructor to ES6 class (like the calendar
module in #3959)
- Replaced manual fetch() + timer handling with HTTPFetcher composition
- Uses structured error objects with translation keys
- Inherits smart retry strategies (401/403, 429, 5xx backoff)
- Inherits timeout handling (30s) and AbortController

**node_helper.js:**
- Updated error handler to use `errorInfo.translationKey`
- Simplified property access (`fetcher.url`, `fetcher.items`)

**Cleanup:**
- Removed `js/module_functions.js` (`scheduleTimer` no longer needed)
- Removed `#module_functions` import from package.json

Part of the HTTPFetcher migration effort started in #4016.
Next candidate: Weather module (client-side → server-side migration).
