Create a customer credit memo

Issues a credit memo against an account through the canonical credit-memo writer (issueCreditMemo; same code path as the internal UI). Posts the per-source_type GL entry (manual/goodwill credits: DR Sales Returns & Allowances / CR Customer Credits liability), increments the account’s spendable credit_balance, assigns a sequential credit_memo_number, and tracks the open balance for future application.

Idempotency: when source_type + source_id are supplied, re-issuing the same triple returns the EXISTING memo with HTTP 200 instead of creating a duplicate. Manual credits without a source_id always create a new memo. If expires_at is omitted the entity’s default credit-expiry policy applies (null = never expires).
