Expanding the Xero Bank Feeds API for non-bank statement data

Summary

• Enables vetted partners to submit non‑bank statement data via the existing Bank Feeds API (POST /FeedConnections, POST /Statements) in beta
• Allows one‑way creation of statement lines for non‑bank sources without affecting existing bank feeds or UI feed discovery
• Uses the same OAuth, scopes, and connection workflow as current bank feeds; only new statements can be created, not updated or deleted
