Your task is to implement the following APIs using .NET 8 and Entity Framework Core:

Method: GET
URL: /api/MembershipPackages
Description: Retrieve all membership packages with registered member count statistics. Supports JSON.

Method: GET
URL: /api/filter-members
Description: Advanced search for members with training duration stats and recent coach assignment logs.

Method: POST
URL: /api/MembershipPackages
Description: Add a new membership package to the gym catalog.

Method: DELETE
URL: /api/MembershipPackages/{packageId}
Description: Remove a membership package from the system.

1. GET /api/MembershipPackages
- Retrieve a list of all membership packages from the database.
- Response Fields:
PackageId (int)
PackageName (string)
Price (decimal)
MemberCount (int): Total number of gym members currently registered under this membership package.

2. GET /api/filter-members
Retrieve a list of gym members with advanced booking performance statistics.
- Filtering Logic:
packageId (int, optional): If specified, return only members registered with this Package ID.

- Error handling: Return 400 Bad Request if minDuration is negative (if provided).
- Sorting: Sort results by JoinDate in descending order (newest members first).

3. POST /api/MembershipPackages
Accept PackageName and Price inside the request body.
- Return: 201 Created along with the complete newly created MembershipPackage entity (ensure navigation properties like Members are returned as empty lists [] instead of null to avoid client integration crashes).
- Error handling: If the package PackageName already exists (case-insensitive check), return 400 Bad Request with message "Membership package name already exists".
