Prohibit showing availability when requested time IS available

JULIA'S ISSUE: Requests 9:15 AM Friday → agent shows availability list instead of booking directly

ROOT CAUSE: Agent not following "complete user info = immediate booking" instructions
- Julia provides: time, date, duration, topic, phone, format (Google Meet)
- 9:15 AM Friday IS available in Peter's calendar
- Agent should book immediately, not ask "Which time would work best?"

FIXES ADDED:
- "DO NOT show availability list if their requested time is available"
- "DO NOT ask 'Which time would work best?' when they already specified a time"
- "WHEN REQUESTED TIME IS AVAILABLE: IMMEDIATELY call create_appointment"

EXPECTED FLOW AFTER FIX:
Julia: "Friday at 9:15 am, 15 minutes, Google Meet..."
→ Agent checks 9:15 AM Friday (available)
→ Agent calls create_appointment immediately
→ Returns real booking confirmation with Google Meet link

No more unnecessary availability lists when user's requested time is free!

Bump version to 1.0.53
