/**
 * Seed the `standard-quote-by-location` template into
 * `standard_quote_document_templates` so it is listed in the quote template
 * dropdown and can be explicitly selected on a quote.
 *
 * The template already exists as code in
 * `packages/billing/src/lib/quote-template-ast/standardTemplates.ts`
 * (buildStandardQuoteByLocationAst) and has been wired into the auto-branch
 * fallback for multi-location quotes. This migration makes it visible to
 * end users.
 *
 * Shape: repeating stack `location-bands` driven by the `groupsByLocation`
 * collection binding. Each iteration renders a location band with:
 *   - a header stack bound to the current group item (location-band-header)
 *   - a dynamic-table bound to `group.items` (location-band-items)
 *   - a subtotal row reading `group.subtotal` (location-band-subtotal)
 *
 * This replaces an earlier two-table approximation (location summary table
 * + flat line items table with a Location column). The primitive powering
 * the repeat is the optional `repeat` on stack nodes — see
 * packages/types/src/lib/invoice-template-ast.ts (TemplateStackNode).
