Foundation: Prepare application code to read from detached table

Description

We need to find a way to use a detached table instead of packages_packages table for specific packages models.

As a primary case, we shouldn't rely for filtering package format on package_type column in the packages_packages table and instead use a dedicated package model.

To avoid any surprises it should work well with the feature flag.

Proposal

• We need to examine all usages of package_type and refactor the code to use a dedicated package model instead.
