Add domain-specific compliance and regulatory fields

[fusion94]

Summary

Certain inventory domains have regulatory requirements that need dedicated support (e.g., firearms require FFL tracking, serial number logging, and transfer records).

Details

• Support optional compliance modules that can be enabled per domain
• Examples:
  • Firearms: Serial number tracking, FFL dealer info, acquisition/disposition log (A&D book), 4473 form tracking, NFA item tracking
  • Chemicals/Hazmat: SDS sheets, hazard classifications, storage requirements
  • Food/Wine: Expiration dates, lot numbers, storage temperature
  • Medical: Lot tracking, expiration, recall management
• Compliance fields should be optional add-ons, not core fields
• Support generating compliance reports

Acceptance Criteria

• Compliance modules can be enabled/disabled per domain
• At least one compliance module is fully implemented as proof of concept
• Compliance data is included in relevant reports
• Required compliance fields are enforced when module is active
