As reported in #4109, the weather module retries much more frequently than expected after network errors. #4092 already fixed the main cause (duplicate fetchers), but the backoff logic in HTTPFetcher still has a gap: once retries are exhausted, calculateBackoffDelay keeps returning a short fixed delay (60s) instead of falling back to reloadInterval. The same problem existed for 5xx errors, where the delay grew to 8× the configured interval.

Inspired by #4110 (thanks @CodeLine9), this PR makes both error paths fall back to reloadInterval after retries are exhausted. I also simplified the catch block, extracted a #shortenUrl() helper for log messages, and added tests for the backoff progression.

When networkErrorCount or serverErrorCount reaches maxRetries,
calculateBackoffDelay produced a fixed short delay instead of
respecting the user's configured reloadInterval.

Skip backoff once retries are exhausted and use reloadInterval
directly. Both network and server error paths now use the same
calculateBackoffDelay strategy for consistency.
- Extract URL truncation into private #shortenUrl() method
- Use #shortenUrl() consistently in all log messages
- Merge duplicate networkErrorCount >= maxRetries checks into a single
  if/else block that handles both delay calculation and logging
- Replace logFn.call(Log, ...) with explicit if/else for clarity
- Remove redundant inline JSDoc for error event
Verify that both network and server errors fall back to reloadInterval
after maxRetries is reached, and that error counts reset on success.

## Release Notes
Thanks to: @cgillinger, @khassel, @KristjanESPERANTO, @sonnyb9
> ⚠️ This release needs nodejs version >=22.21.1 <23 || >=24 (no change
to previous release)

[Compare to previous Release
v2.35.0](v2.35.0...v2.36.0)

This release falls outside the quarterly schedule. We opted for an early
release due to:
- Security fix for the internal cors proxy
- API change of the weather provider smi
- Several bug fixes

### Breaking Changes

The cors proxy is now disabled by default. If required, it must be
explicitly enabled in the `config.js` file. See the
[documentation](https://docs.magicmirror.builders/configuration/cors.html).

### ⚠️ Security

You can find several publicly accessible MagicMirror² instances.

This should never be done. Doing so makes your entire configuration,
including secrets and API keys, publicly visible. Furthermore, it allows
attackers to target the host; this is only prevented beginning with this
release.

Public MagicMirror² instances should always run behind a reverse proxy
with authentication.
