Add Agent 0x99 phone support dialogue script for Mission 4

Created m04_phone_agent0x99.ink (510 lines) - strategic guidance system
providing event-triggered phone support throughout the mission.

Key features:
- Handler confidence tracking (0-100) affecting dialogue tone
- Event-triggered conversations (server room, attack identified)
- Adaptive guidance based on player progress and choices
- Player-initiated help system (priorities, intel, tactical hints)
- Voltage capture vs. speed guidance for final phase
- Multi-stage mission progression support

Implements dialogue planning from Stage 6 for Agent 0x99 phone contact.
