Start CQRS refactoring: Create Osiris client crate

- Added workspace structure to Osiris Cargo.toml
- Created osiris-client crate for query operations (GET requests)
- Implemented generic get(), list(), query() methods
- Added KYC, payment, and communication query modules
- Created comprehensive refactoring plan document

CQRS Pattern:
- Commands (writes) → Supervisor client → Rhai scripts
- Queries (reads) → Osiris client → REST API

Next steps:
- Implement Osiris server with Axum
- Restructure SDK client by category (kyc/, payment/, etc.)
- Update FreezoneClient to use both supervisor and osiris clients
