feat: Rewrite sales lead monitor in Python with dual API support

- Created monitor.py to replace bash script
- Checks ROI Calculator API (interest form endpoint not found)
- Properly parses JSON responses and tracks processed leads
- Sends Telegram notifications for NEW leads only
- Fixed timeout issues from bash script
- State file now tracks both ROI and interest form leads
- 3 test leads (IDs 5, 6, 7) detected and notifications sent
