Export functions for subshell access (CRITICAL FIX)

HTTP monitoring runs in subshells (from tail pipe) but functions
were not exported, making them unavailable in those subshells.

Exported functions:
- write_ip_data_to_file (writes scores to file)
- update_ip_intelligence (updates IP scores)
- get_ip_intelligence (reads IP data)
- get_threat_level (calculates threat level)
- get_threat_color (gets display color)

This fixes the critical bug where HTTP attacks reached Score:100
but were never blocked because scores weren't written to ip_data file.

Without exports: function called in subshell = command not found
With exports: function available in all child processes
