Refs #65

GET /api/events now returns {events, errors}, naming every failed calendar/account even on partial failure; the client shows a per-calendar sidebar warning badge plus a toast, and partial results are not cached. parseCalendarList/parseEventList throw on anything that is not a complete DAV multistatus, event hrefs are no longer filtered by a case-sensitive '.ics' suffix, and getCalendarShares throws on 5xx/auth errors (404/405/501 still mean 'sharing unsupported' per #269). Product choices: no compat shim for the old array shape, account-level errors badge all of that account's calendars.
