Found this while debugging.
The `hasCalendarURL` function does a check if the url is in the config.
But the calendar sees only his own config part, so this check is always
true (tested with more than one calendar module in `config.js`).
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).
Since the project's inception, I've missed a clear separation between
default and third-party modules.
This increases complexity within the project (exclude `modules`, but not
`modules/default`), but the mixed use is particularly problematic in
Docker setups.
Therefore, with this pull request, I'm moving the default modules to a
different directory.
~~I've chosen `default/modules`, but I'm not bothered about it;
`defaultmodules` or something similar would work just as well.~~
Changed to `defaultmodules`.
Let me know if there's a majority in favor of this change.
