The update removes an unrelated point of sale manager permission from shared accounting test setup so permission checks better reflect real usage. Point of sale tests now receive that access only where needed, and product users gain read-only access to Urban Piper status data.

The `group_pos_manager` was previously reintroduced in `AccountTestInvoicingCommon` due to demo data changes. However, this group is unrelated to the `account` module and may mask real permission issues in tests.

This commit removes the group from the common test setup and adds it explicitly in the relevant PoS test cases where needed.

Grants read-only access to `product.urban.piper.status` for product users.

A subscription project helper was renamed to stay aligned with the related sales project update. This prevents a mismatch that could affect revenue item retrieval for subscription projects, with no expected change to day-to-day workflows.

Match the method name from `sale_project` changed in community side PR.
