Fix bugs in timezone handling and local file support

- Fix timezone conversion for recurrence exceptions
- Fix type safety: use PathInfo type instead of any
- Fix Windows path detection to support forward slashes (C:/)
- Fix file URL normalization for Windows (file:///C:/) and Unix
- Add safety check for setTimeout DOM manipulation in settings
- Add CSS fallback for themes without --interactive-success variable
- Improve error message handling when response.text is undefined
