feat: add conversational property onboarding flow

When user says 'add my home' without property details, return a warm
structured prompt asking for address, purchase price, current value,
mortgage balance, and monthly rent instead of calling add_property
with empty/zero values.

Detection: message lacks a price pattern (\$[\d,]+, \d+k, \d{5,}).
If message already contains a price, proceed directly to add_property.
