[31388f42] Feature: Integrate Roboplanet Contact Forms into Lead Engine

This commit integrates the Roboplanet website contact form submissions into the Lead Engine, allowing them to be processed alongside TradingTwins leads.

Key changes:
- **Database Schema Update (db.py):** Added a new source column to the leads table for tracking lead origin (TradingTwins or Website-Formular). Includes a migration check to safely add the column.
- **Improved HTML Parsing (ingest.py):** Refined the `parse_roboplanet_form` function to accurately extract data from the specific HTML structure of Roboplanet contact form emails.
- **Enhanced Ingestion Logic (trading_twins_ingest.py):**
    - Renamed `fetch_tradingtwins_emails` to `fetch_new_leads_emails` and updated it to fetch emails from both lead sources.
    - Modified `process_leads` to dynamically select the correct parser based on email subject.
    - Ensured `source` field is correctly populated and `is_low_quality` checks are applied for both lead types.
- **UI Enhancement (app.py):** Updated the Streamlit UI to visually distinguish lead types with icons and improved the "Low Quality Lead" warning message.

This feature enables a unified processing pipeline for different lead sources and provides better visibility in the Lead Engine dashboard.
