[PS-1265] fix on install hook

Objective

Fix oninstall hook for manifest v3.

I'm also trying out a way of organizing Manifest V3 factories for command initialization. In effect, it's hiding the initialization specifics within a factory method and forcing only the minimum required parameters for all dependent services to be provided.

This is a reasonable pattern until services are decoupled to the point that we just want simple initializers.

Code changes

Most of the changes are with creating factories. Other changes are:

• background: add onInstall listener
• main.background: use factories
• onInstallListener: Copied from runtime.background (It still exists there for mv2 usage).
