Fix advisory inheritance and overrides

[adobes1]

Fixes the following:

1. Previously, when retrieving advisory IDs of a release which had advisories! defined, art-dash would use the advisories defined in the basis version (it would also not retrieve the corresponding jira ticket)
2. When merging current_advisories and basis_advisories (or basis_override_advisories), art-dash would layer basis_advisories (or basis_override_advisories) over current_advisories. Now it is the opposite.

Also temporarily replace ./install.sh in the Dockerfiles with pip3 install -e artcommon/ -e doozer/ -e elliott/ -e pyartcd/ because ./install.sh is now using uv package manager and so far I couldn't get it to work inside the Dockerfiles.
