[core] refactor: extract and centralize HTTP fetcher (#4016)

## Summary PR [#3976](https://github.com/MagicMirrorOrg/MagicMirror/pull/3976) introduced smart HTTP error handling for the Calendar module. This PR extracts that HTTP logic into a central `HTTPFetcher` class. Calendar is the first module to use it. Follow-up PRs would migrate Newsfeed and maybe even Weather. **Before this change:** - ❌ Each module had to implemented its own `fetch()` calls - ❌ No centralized retry logic or backoff strategies - ❌ No timeout handling for hanging requests - ❌ Error detection relied on fragile string parsing **What this PR adds:** - ✅ Unified HTTPFetcher class with intelligent retry strategies - ✅ Modern AbortController with configurable timeout (default 30s) - ✅ Proper undici Agent for self-signed certificates - ✅ Structured error objects with translation keys - ✅ Calendar module migrated as first consumer - ✅ Comprehensive unit tests with msw (Mock Service Worker) ## Architecture **Before - Decentralized HTTP handling:** ``` Calendar Module Newsfeed Module Weather Module ┌─────────────┐ ┌─────────────┐ ┌─────────────┐ │ fetch() own │ │ fetch() own │ │ fetch() own │ │ retry logic │ │ basic error │ │ no retry │ │ error parse │ │ handling │ │ client-side │ └─────────────┘ └─────────────┘ └─────────────┘ │ │ │ └───────────────────────┴───────────────────────┘ ▼ External APIs ``` **After - Centralized with HTTPFetcher:** ``` ┌─────────────────────────────────────────────────────┐ │ HTTPFetcher │ │ • Unified retry strategies (401/403, 429, 5xx) │ │ • AbortController timeout (30s) │ │ • Structured errors with translation keys │ │ • undici Agent for self-signed certs │ └────────────┬──────────────┬──────────────┬──────────┘ │ │ │ ┌───────▼───────┐ ┌────▼─────┐ ┌──────▼──────┐ │ Calendar │ │ Newsfeed │ │ Weather │ │ ✅ This PR │ │ future │ │ future │ └───────────────┘ └──────────┘ └─────────────┘ │ │ │ └──────────────┴──────────────┘ ▼ External APIs ``` ## Complexity Considerations **Does HTTPFetcher add complexity?** Even if it may look more complex, it actually **reduces overall complexity**: - **Calendar already has this logic** (PR #3976) - we're extracting, not adding - **Alternative is worse:** Each module implementing own logic = 3× the code - **Better testability:** 443 lines of tests once vs. duplicating tests for each module - **Standards-based:** Retry-After is RFC 7231, not custom logic ## Future Benefits **Weather migration (future PR):** Moving Weather from client-side to server-side will enable: - **Same robust error handling** - Weather gets 429 rate-limiting, 5xx backoff for free - **Simpler architecture** - No proxy layer needed Moving the weather modules from client-side to server-side will be a big undertaking, but I think it's a good strategy. Even if we only move the calendar and newsfeed to the new HTTP fetcher and leave the weather as it is, this PR still makes sense, I think. ## Breaking Changes **None** ---- I am eager to hear your opinion on this 🙂
