Retrieve one invoice, with its lines

GET/lokta-lms/api/v1/invoices/{id}

Returns one partner invoice with its lines.

gst_treatment and gst_rate_pct are snapshotted onto the document. A partner who registers for GST next month must not retrospectively change the tax on an invoice already issued; the rate that applied is a fact about this document, not about the partner today. Do not re-derive tax from the partner's current details.

Under reverse charge, gst_rate_pct is null and gst_amount is "0.00": the recipient bears the tax, so the invoice carries none. That is different from a zero rate, and rendering it as "GST 0%" would state something false.

Lines are grouped by fee line, not by loan; "Sourcing fee · 26,250", not a thousand loan-level rows. Every loan-level figure survives in /fee-runs/{id}/accruals, so the summary can always be opened up: the invoice is the statement, the accruals are the evidence.

invoice_number is gap-free within its financial year and is kept on cancellation; GST requires a consecutive series, so a cancelled number stays spent rather than being reissued to a different document.
