fix(caldav): discover calendars via principal/calendar-home-set #8259 (#8278)
* fix(caldav): discover calendars via principal/calendar-home-set #8259

The CalDAV Events plugin populated its calendar dropdowns with a single
Depth:1 PROPFIND on the exact URL the user entered, keeping only
responses whose resourcetype is <calendar>. Users paste the advertised
CalDAV root (Nextcloud /remote.php/dav, Fastmail /dav/), where calendars
live one or two collection levels deeper, so the request succeeds but
lists no calendars. The dialog then showed a green 'Options loaded' tick
with empty dropdowns (loadOptions resolved with an empty array, no
error), and the Schedule showed no events because no calendar could be
selected.

Rewrite discoverCalendars to do RFC 4791 service discovery: try the
entered URL directly (back-compat for a pasted calendar-home), else
PROPFIND current-user-principal, then calendar-home-set, then enumerate
the home collection.

Discovery now follows server-controlled hrefs, so harden resolveHref to
resolve via the URL constructor and refuse any off-origin target (the
SSRF boundary, since credentials attach to every request), and drop
untrusted server data from thrown error messages. De-duplicate the XML
parse-error guard into a shared parseXmlDoc.

Add discovery test coverage (previously none), including cross-origin
href refusal.

* test(caldav): assert request origin instead of URL substring

CodeQL flagged the cross-origin discovery test's url.includes('evil...')
check (js/incomplete-url-substring-sanitization). Parse each requested
URL and assert its origin equals the entered server origin instead — a
stronger, alert-free assertion that no credentialed request escaped
off-origin.
