fix(server): branches activation not marking bills and payments with primary branch

When activating the multi-branches feature, existing bills, vendor credits,
and bill payments were not being marked with the default primary branch.

Changes:
- Add missing @Inject decorators to BillActivateBranches, VendorCreditActivateBranches,
  and BillPaymentsActivateBranches services
- Create BillBranchesActivateSubscriber to listen to onActivated event
- Create VendorCreditBranchesActivateSubscriber to listen to onActivated event
- Register BillPaymentsActivateBranches and PaymentMadeActivateBranchesSubscriber
  in BranchesModule
- Add branch object to BillResponseDto for API responses
- Add branch to BillTransformer includeAttributes

Fixes: #935
