Kristjan ESPERANTO ab3108fc14 [calendar] refactor: delegate event expansion to node-ical's expandRecurringEvent (#4047)
node-ical 0.25.x added `expandRecurringEvent()` — a proper API for
expanding both recurring and non-recurring events, including EXDATE
filtering and RECURRENCE-ID overrides. This PR replaces our hand-rolled
equivalent with it.

`calendarfetcherutils.js` loses ~125 lines of code. What's left only
deals with MagicMirror-specific concerns: timezone conversion,
config-based filtering, and output formatting. The extra lines in the
diff come from new tests.

## What was removed

- `getMomentsFromRecurringEvent()` — manual rrule.js wrapping with
custom date extraction
- `isFullDayEvent()` — heuristic with multiple fallback checks
- `isFacebookBirthday` workaround — patched years < 1900 and
special-cased `@facebook.com` UIDs
- The `if (event.rrule) / else` split — all events now go through a
single code path

## Bugs fixed along the way

Both were subtle enough to go unnoticed before:

- **`[object Object]` in event titles/description/location** — node-ical
represents ICS properties with parameters (e.g.
`DESCRIPTION;LANGUAGE=de:Text`) as `{val, params}` objects. The old code
passed them straight through. Mainly affected multilingual Exchange/O365
setups. Fixed with `unwrapParameterValue()`.

- **`excludedEvents` with `until` never worked** —
`shouldEventBeExcluded()` returned `{ excluded, until }` but the caller
destructured it as `{ excluded, eventFilterUntil }`, so the until date
was always `undefined` and events were never hidden. Fixed by correcting
the destructuring key.

The expansion loop also gets error isolation: a single broken event is
logged and skipped instead of aborting the whole feed.

## Other clean-ups

- Replaced `this.shouldEventBeExcluded` with
`CalendarFetcherUtils.shouldEventBeExcluded` — avoids context-loss bugs
when the method is destructured or called indirectly.
- Replaced deprecated `substr()` with `slice()`.
- Replaced `now < filterUntil` (operator overloading) with
`now.isBefore(filterUntil)` — idiomatic Moment.js comparison.
- Fixed `@returns` JSDoc: `string[]` → `object[]`.
- Moved verbose `Log.debug("Processing entry...")` after the `VEVENT`
type guard to reduce log noise from non-event entries.
- Replaced `JSON.stringify(event)` debug log with a lightweight summary
to avoid unnecessary serialization cost.
- Added comment explaining the 0-duration → end-of-day fallback for
events without DTEND.

## Tests

24 unit tests, all passing (`npx vitest run
tests/unit/modules/default/calendar/`).

New coverage: `excludedEvents` with/without `until`, Facebook birthday
year expansion, output object shape, no-DTEND fallback, error isolation,
`unwrapParameterValue`, `getTitleFromEvent`, ParameterValue properties,
RECURRENCE-ID overrides, DURATION (single and recurring).
