Commercial: customer type is only determined on active B2B features, not based on the actual account type

### Shopware Version

6.7.8.2 w/ SwagCommercial 7.8.2

### Affected area / extension

Platform(Default)

### Actual behaviour

The account type of a customer is displayed as B2C even when the account has been created as a business account and the account_type in the customer table is set to 'business'. It seems that the account type is solely determined based on active Commercial B2B features.

Currently:

- B2B customer has no B2B-Features active -> Shows up as B2C account
- B2C customer has B2B-Features active -> Shows up as B2B account

Seems to be related to https://github.com/shopware/shopware/issues/13953

### Expected behaviour

B2B Customers without active B2B features still show up as business customers

### How to reproduce

- In a shop with Commercial, create a business account, but do not activate any B2B features
- Go to the overview and check the account type, it will show as B2C

Reproduce the account-type display in the overview using a business account with no active B2B features, then trace how the customer table's account_type value is used. Compare the behavior with the related issue #13953. Done means business accounts still display as B2B customers regardless of active Commercial B2B features.
