Add tenant suport

[juan-malbeclabs]

This pull request introduces comprehensive support for "tenant" management across the onchain programs, SDKs (Python/TypeScript), and both the doublezero and doublezero-admin CLI tools. The changes add a new Tenant account type, implement program-derived address (PDA) derivation for tenants, and provide full CRUD and administrator management capabilities in both the SDKs and CLI interfaces.

Major changes include:

Onchain Programs and Account Model

• Added a new Tenant account type, with immutable code-based PDA derivation, support for VRF ID, administrator management, and reference counting for safe deletion. New instructions for adding/removing administrators and updating/deleting tenants are included. Reference counting is integrated into user/tenant relationships for safe resource management.

SDK Enhancements

• Python SDK:
  • Added Tenant account type and deserialization logic in state.py. [1] [2]
  • Implemented derive_tenant_pda in pda.py for deterministic tenant address derivation. [1] [2]
• TypeScript SDK:
  • Added ACCOUNT_TYPE_TENANT, Tenant interface, and deserialization logic in state.ts. [1] [2]
  • Implemented deriveTenantPda in pda.ts for code-based PDA derivation. [1] [2]

CLI Additions

• doublezero and doublezero-admin CLIs:
  • Added a new tenant subcommand with support for create, update, delete, get, list, add-administrator, and remove-administrator operations. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11]
  • Implemented the AddAdministratorTenantCliCommand for adding administrators to tenants.

Smartcontract CLI Integration

• Extended the CliCommand trait and its implementation to support all tenant-related operations (create, get, list, update, delete, add/remove administrator), and exposed these via the CLI. [1] [2] [3] [4] [5]

Documentation

• Updated the CHANGELOG.md to document all new tenant-related features, CLI commands, and SDK additions.

Testing Verification

• Show evidence of testing the change

Odd that this is 13 and not 12?

[juan-malbeclabs]

Because ResourceExtension is 12.

ResourceExtension = 12,
