Merged PR 1996: fix(crm): consolidate customer feature selection logic

fix(crm): consolidate customer feature selection logic

Introduce centralized `getEnabledCustomerFeature` helper to standardize
feature selection across components. Replaces inconsistent filtering
approaches with unified logic that prioritizes 'd-account' and
'd-no-account' features.

Changes:
- Add `getEnabledCustomerFeature` helper with unit tests
- Add `CustomerFeatureKey` and `CustomerFeatureGroup` enums
- Update customer-order-details-header component
- Update pickup-shelf-details-header component
- Update customer-result-list components
- Update order-details-main-view component
