## Summary
When a Super Admin creates a new account via the Administrate dashboard,
the `manually_managed_features` field (a virtual attribute stored in
`internal_attributes` JSON) is passed to `Account.new(...)`, raising
`ActiveModel::UnknownAttributeError`. The existing `update` action
already strips this param — this fix adds the same handling to `create`.

## Type of change
- [x] Bug fix (non-breaking change which fixes an issue)
## How to reproduce
1. Log in as Super Admin
2. Navigate to Accounts → New
3. Fill in the form (with or without manually managed features selected)
4. Submit → `ActiveModel::UnknownAttributeError: unknown attribute
'manually_managed_features' for Account`
## What changed
- Added a `create` override in
`Enterprise::SuperAdmin::AccountsController` that strips
`manually_managed_features` from params before calling `super`, then
persists them via `InternalAttributesService` after the account is
saved.
