Ramp: Payment lookup

Read-only lookup of vendor bill payments and payment status. Use when: 'did we pay', 'payment status', 'check if paid', 'verify payment', 'was this bill paid', 'when was this invoice paid', 'payment confirmation'. Do NOT use for: approving, rejecting, or otherwise changing a bill (use ramp-manage-bills), spend analysis across vendors (use ramp-spend-analysis), or a cross-product approval queue (use ramp-approval-dashboard).
