Overview

Marks a proposal as accepted. The proposal's status changes to either Accepted or Accepted with Changes depending on whether the proposal has been modified since it was quoted. Acceptance may also generate a policy number if configured.

What this endpoint does:

1. Loads the proposal by proposalID
2. Validates the proposal can be accepted (permission, status, business rules, validations)
3. Checks that any online payment has not been refunded
4. If the proposal was modified since quoting: sets status to Accepted with Changes; otherwise Accepted
5. For renewals: generates or reuses a policy number
6. For other types: generates a policy number if the PolicySet is configured to do so on accept
7. Logs the action via workflow log and fires a status change event

Note: This endpoint does not set billingFrequency, installmentFees, totalCost, or securityDeposit on the proposal. If you need to set billing details, update the proposal through a separate call before or after acceptance.f
