feat: add Multi-Tenancy

[daspayalll]

Description


Enable Gymie to support multiple tenants within a single application installation, ensuring complete data isolation and scoped access. Each tenant will operate independently with their own set of data, users, resources, and configurations, while a super admin will have the ability to oversee and manage all tenants from a centralized interface.

Checklist

• Implement multiple tenancy for every gym members
• Implement tenant identification middleware
• Scope all models and queries by tenant
• Update Filament resources
• Add super admin role for managing all tenants

Note: Assign super admin at least one people from the gym management system so they can have all the access control across the application.
