fix: Properly decode HTML entities in chat messages

- Fix ' not being decoded to apostrophe
- Decode HTML entities when loading messages from localStorage
- Improve server-side HTML entity decoding to handle all variations
- Replace hardcoded ' in static text with regular apostrophes
- Add support for more HTML entity variations (rsquo, lsquo, etc.)
