Returns a detailed financial summary for a single landlord profile.

Overview

Provides the same data as the list endpoint but with additional details:

• Full profile information (name, reference, nature, email)
• Cash balance and retained provisions
• List of managed assets (up to 20) with references and addresses
• Pending payment orders count and total

Use cash_balance.value_in_cents as the landlord's current available position after accounting
entries. Do not derive it by subtracting landlord_rental_fees_in_cents from a lease's
received_rent_amount: landlord_rental_fees_in_cents represents one-off letting fees, not
recurring management fees.

Returns 404 if the profile does not exist or is not a landlord.
