This commit refactors the bot's architecture to dynamically load and build conversation flows from JSON files instead of hardcoding them in Python.
- Added to read flow definitions from the directory and dynamically build s.
- Refactored to use the new flow builder and load all conversation handlers at startup.
- Moved hardcoded links to environment variables for better configuration.
- Updated to support conditional branching for 'Other' options, using a field to define state transitions.
- Updated with the new link variables.
