feat: add folder URL support to folder export command

- Add Folder.from_url() method to parse folder URLs and extract IDs
- Support multiple URL patterns: /spaces/SPACE/folders/ID, /spaces/SPACE/pages/folders/ID
- Update folders command to accept both IDs and URLs with automatic detection
- Add comprehensive unit tests for URL parsing (4 new tests covering different patterns)
- Update README.md with folder URL usage examples
- Fix test infrastructure in conftest.py to handle module-level Confluence instance

All 89 unit tests passing. Folder export now supports the same flexible input
methods as page exports, allowing users to easily export folders by copying
URLs from their browser.
