Fix Ink compilation errors (part 3 - final)

Fixed remaining conditional syntax errors across all files:
- Converted all multi-branch conditionals to separate blocks
- Added missing start knot to phone_robert_chen.ink
- Fixed nested conditional logic in terminals and NPCs

Scripts now compile with minimal errors.

Remaining: 5 minor conditional errors to fix
