Fix Outlook calendar fetching issues in Obsidian 1.9.0

Browse source 
- Fix calendar fetching broken by Chromium 138 header validation
- Improve Outlook calendar compatibility with simplified headers
- Add robust HTML error page detection and multiple retry strategies
- Enhance error handling with user-friendly notifications
- Add calendar data validation to ensure valid iCalendar format
- Update to version 1.6.3

Resolves issues where Outlook calendars returned HTML error pages
instead of calendar data when using complex browser headers.
