Fix Ink compilation errors (part 1)

- Add missing VAR declarations
- Replace EXTERNAL declarations with proper VARs
- Fix conditional syntax (add proper else clauses)
- Replace -> END with #exit_conversation and loop to start
- Add start knots to operative dialogue files

Files fixed:
- m04_opening_briefing.ink
- m04_npc_operative_cipher.ink
- m04_npc_operative_relay.ink
- m04_npc_operative_static.ink
- m04_npc_voltage.ink (partial)

Remaining to fix:
- m04_npc_robert_chen.ink
- m04_phone_agent0x99.ink
- m04_phone_robert_chen.ink
- m04_terminal_attack_trigger.ink
- m04_terminal_scada_display.ink
- m04_closing_debrief.ink
