+// SetMiddlewareLogger
+//
+// Description:
+//
+//	Registers a Gin middleware that attaches a custom logger instance
+//	to every incoming request via the Gin context. This allows other
+//	middleware and handlers to access the logger using:
+//
+//	    logger := c.MustGet("logger").(*logging.Logger)
+//
+// Parameters:
+//   - r:      The Gin engine to which the middleware is applied.
+//   - logger: A pointer to the application's custom logger.
+//
+// Usage:
+//
+//	SetMiddlewareLogger(router, logger)

+//
+// Description:

+//	A Gin middleware that performs authentication using a JWT token stored
+//	in a cookie named "access_token". It validates the token and extracts
+//	the user's role from the claims, storing it in the Gin context.
+//
+// Behavior:
+//   - Requires that SetMiddlewareLogger was used earlier to inject the logger.
+//   - If the JWT cookie is missing or invalid, it aborts the request with
+//     an appropriate HTTP error (401 or 500).

+//
+// Description:

+//	A role-based authorization middleware. It checks whether the authenticated
+//	user (based on the "role" set in AuthMiddleware) has permission to access
+//	the given route. The check is performed by comparing the requested URL
+//	path against the user’s allowed permissions.
+//
+// Parameters:
+//   - suffix: A URL prefix to trim from the request path before matching
+//     permissions (e.g., "/api/v1").
+//
+// Behavior:
+//   - Fetches the user role from Gin context.
+//   - Uses aH.GetRoleByKey() to retrieve role records and permissions.
+//   - Grants access (calls c.Next()) if a matching permission is found.
+//   - Denies access (401 Unauthorized) if no permission matches.
+//
+// Usage:
+//
