Auto-add an onboarding fee

Standard fees get forgotten on some quotes and added inconsistently on others, which shows up later as revenue leakage.

Manage Line Items adds the fee automatically when a deal reaches the right stage, so every quote carries it.

1. 1Enrol deals when they reach the stage where the fee applies.
2. 2Add Manage Line Items with Add a line item to the deal.
3. 3Give it a name, unit price and quantity so every quote is consistent.
4. 4Use the returned line item ID in later steps if you need it.

• Add line items with name, price, quantity and SKU
• Update all line items or filter by any line item property
• Remove matching line items or clear the deal
• Values can come from deal properties
