Expand ERP modules and add dual AGPL/commercial licensing

[Asadalisabeni]

What changed

• expanded Inventory with warehouse-aware stock, transfers, adjustments, opname, reversals, and dynamic negative-stock authorization
• added Purchasing flows for purchase requests, purchase orders, goods receipts, and suppliers
• added CRM, Accounting, HR, and User Management modules
• introduced database-backed role permissions with full Manager authorization configurable from the UI
• redesigned the application shell and dashboard with a responsive Tailwind interface
• completed the as-built Inventory Service Design Specification with contracts, invariants, diagrams, concurrency controls, recovery procedures, limitations, ADRs, and test traceability
• added AGPL-3.0-only community licensing plus a separate commercial/OEM licensing path
• added COMMERCIAL-LICENSE.md, CONTRIBUTING.md, CLA.md, and TRADEMARKS.md
• updated Guzzle to 7.15.1 to resolve dependency security advisories

Why

This turns the inventory prototype into a locally runnable, auditable portfolio platform while preserving an open community edition and a commercial licensing option for proprietary, OEM, reseller, and white-label use. The architecture documentation now reflects the actual Laravel 13 implementation rather than the earlier unfinished design.

User and developer impact

Managers receive all permissions by default and permissions can be changed inside the application without source-code edits. Inventory writes remain immutable and transactional. Existing installations should run the included migrations and seed the permission/account definitions before use. Future contributors have an authoritative service contract and extension checklist.
