feat: Implement tenant-aware configuration system

- Added tenant verification checklist in TENANT_VERIFICATION.md for system validation. - Created tenant_config.py to manage tenant-specific configurations with global defaults and per-tenant overrides. - Introduced tenant_guards.py for route protection based on module availability. - Developed tenant_resolver.py for identifying active tenants from requests using subdomains and headers. - Added tenant_templates.py for Jinja2 template helpers to check module visibility. - Created error_403.html for custom 403 error handling. - Defined tenants.json for tenant configurations and module management. - Implemented unit tests in test_tenant_system.py to ensure functionality of tenant system components.
