Pull request overview
This PR implements comprehensive backend support for multi-network token standard compliance and enterprise-grade auditability for the BiatecTokensApi. The implementation enables customers to create and manage tokens with explicit standard profiles, receive clear validation feedback, and maintain durable audit trails for compliance and troubleshooting.
Changes:
- Added Token Standard Registry supporting 5 standards (Baseline, ARC-3, ARC-19, ARC-69, ERC-20)
- Implemented validation services with deterministic error codes and user-friendly messages
- Created 3 new REST API endpoints for standards discovery and preflight validation
- Enhanced audit trail model with 7 new fields for validation tracking
- Added 55 comprehensive unit and integration tests (100% passing)

This foreach loop implicitly filters its target sequence - consider filtering the sequence explicitly using '.Where(...)'.

This foreach loop immediately maps its iteration variable to another variable - consider mapping the sequence explicitly using '.Select(...)'.

<issue_title>Backend: token standard compliance profiles and audit trail</issue_title>
<issue_description>## Summary
Build backend support for multi-network token standard compliance and enterprise-grade auditability so the platform can deliver a SaaS-first, mainnet-ready experience. The goal is to let customers create and manage tokens with an explicit standard profile, receive clear validation feedback, and maintain a durable audit trail for compliance and troubleshooting. This aligns with the product vision by making the API a trusted system of record for token issuance and lifecycle management, rather than a thin helper service. The work focuses on backend capabilities that can power the current and planned frontend flows without requiring major UX changes.
Business Value
Enterprise customers and serious builders increasingly evaluate token platforms based on standards compliance, risk posture, and long-term maintainability. By adding explicit token standard profiles and rigorous metadata validation, we reduce the risk of non-compliant assets reaching production. That reduces support load, avoids negative wallet experiences, and prevents reputational damage when tokens appear incorrectly in explorers or custodial wallets. A dedicated audit trail creates a defensible record for compliance inquiries, internal QA, and customer success troubleshooting, which is essential for higher-tier SaaS contracts. This also enables new monetization levers: advanced validation rules and compliance reporting can be offered as premium or enterprise plan features, supporting revenue growth beyond simple token creation. The feature set will close parity gaps with competitor platforms that already advertise standards support and compliance readiness, and it will improve conversion by giving prospects tangible assurance that the backend enforces best practices rather than relying on user discipline.
Operationally, standards-aware validation improves the quality of tokens issued through the platform, which reduces downstream support tickets and reduces the need for emergency patches. It also decreases the likelihood of customer churn due to broken wallet rendering, missing metadata, or irreversible on-chain mistakes. For the product vision, a standards-compliant backend creates a stable foundation for SaaS-first user flows, payment enforcement, and ecosystem integrations described in the roadmap. It is a critical prerequisite for future features such as automated wallet integrations, marketplace compatibility, and compliance exports. This initiative also improves internal velocity because the backend will have a clear, extensible model for standards, making it easier to add new networks or metadata rules without ad hoc logic scattered across endpoints.
