This PR simplifies the customers model by removing all the complex transformation logic and replacing it with a simple SELECT * FROM {{ ref('stg_customers') }}.

Changes Made

• Replaced the entire SQL file with a single SELECT statement
• Removed CTEs for orders, payments, signups, customer_orders, customer_payments, and final
• Model now simply passes through all columns from stg_customers

Impact

• The customers model will now only contain the basic customer information from the staging layer
• All derived metrics (first_order, most_recent_order, number_of_orders, customer_lifetime_value, etc.) will be removed
• The model structure will match exactly what's in stg_customers
