Three-step self-service quoting flow on the customer portal: - Step 1: Upload part (STL/PDF) or enter manual measurements + material - Step 2: Select coating config from card grid with specs and thickness - Step 3: View estimated price range and submit quote request Adds dependency on fusion_plating_configurator for fp.coating.config and fp.pricing.rule models. Price estimation uses the same rule-matching logic as the backend configurator with a +/-15-25% range. Dashboard updated with prominent "Get a Quote" button and portal sidebar entry. Breadcrumbs added for configurator pages. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
