feat: Expand social media analyzer to support Kuaishou

This commit adds support for the Kuaishou social network to the social media analyzer.

- Adds 'kuaishou' to the list of supported platforms in `social_media_analyzer/main.py`.
- Adds the legitimate domains for Kuaishou (`kuaishou.com`, `kwai.com`, `kwai.net`) to `social_media_analyzer/heuristics.py`.
- Adds test cases to `social_media_analyzer/test_runner.py` to verify the new functionality.
