Enhance user plan management and update related endpoints

- Added new configuration options for user plans in `.env.example`, including `Plans__MaxCustomConfigCount` and `Plans__MinCustomConfigCount`. - Introduced `MapPlanEndpoints` in `Program.cs` to handle plan-related API routes. - Implemented `SetUserPlan` endpoint in `RoleEndpoints` to allow admins to assign plans to users. - Removed deprecated role request approval endpoints from `AdminSupportEndpoints`. - Updated `ITelegramNotifier` and related classes to reflect changes in role request handling and payment notifications. - Refactored role management commands to remove `MaxConfigs` and focus on `MaxIpLimit` and billing settings. - Enhanced billing request handling to accommodate plan changes instead of role changes. - Updated various interfaces and command handlers to support new plan management features.
