Title: Bug: get_quotation_url Throws AttributeError: 'NoneType' object has no attribute 'get' if no address is set for organisation

[melgo-tb]

Description

When clicking the Create Quotation button from the Deals page, an AttributeError occurs if the organization address is not set. This happens in the get_quotation_url function inside erpnext_crm_settings.py, where get_organization_address(organization) returns None, causing an attempt to access .get("name") on a NoneType object.

AttributeError: 'NoneType' object has no attribute 'get'
address = get_organization_address(organization).get("name") if organization else None

Steps to Reproduce:

1. Open the Deals page in Frappe CRM.
2. Click Create Quotation when the organization does not have an address set.
3. The system throws an AttributeError, breaking the workflow.

Proposed Fix:

Modify the line to check for None before accessing .get("name"):

address = get_organization_address(organization)
address_name = address.get("name") if address else None
