docs: sync purpose of payment codes with OpenAPI schema

[claude]

Summary

• Added FAMILY_SUPPORT and SALARY_PAYMENT to the documented purpose of payment codes in the cross-currency transfers guide

These values were added to the OpenAPI schema in PR #592 (commit 460f14d) but the Mintlify documentation wasn't updated.

Changes

Documentation (mintlify/):

• mintlify/snippets/sending/cross-currency.mdx - Added missing purpose of payment codes to match the schema

Not updated (no changes needed)

• Contact verification endpoints (PR feat(customers): contact (email/phone) verification surface #557): Already documented in mintlify/snippets/kyc/kyc-unregulated.mdx
• Stablecoin provider accounts (PR [brale-link] Add stablecoin provider account API surface #594): New API surface - not referenced in existing guides
• Kotlin sample app: Uses SDK factory method for PurposeOfPayment which auto-supports new values
• Grid Visualizer: Uses 'GIFT' as example value which remains valid

Greptile Summary

This PR syncs the cross-currency transfers guide with the OpenAPI schema by adding FAMILY_SUPPORT and SALARY_PAYMENT to the documented purpose-of-payment codes.

• Both values are present in openapi/components/schemas/quotes/PurposeOfPayment.yaml (and the bundled mintlify/openapi.yaml) and are inserted in the correct position before OTHER, matching the schema order exactly.
• No other documentation files reference the full purpose-of-payment enum, so the single-file change is complete and sufficient.

Confidence Score: 5/5

Documentation-only change that adds two enum values already present in the OpenAPI schema — safe to merge.

The change is a two-line addition to a Markdown accordion, verified against the canonical schema source. No code is altered, no logic is affected, and no other documentation files enumerate the purpose-of-payment codes, so nothing else needs updating.

No files require special attention.

Important Files Changed
