fix: batch authservice checksum updates

[UnicornChance]

Description

Currently we apply a new checksum to the authservice deployment for each chain addition, update, or deletion. This results in multiple applies, sometimes for a single package.

Batch per packages so that a package with multiple authservice clients only results in one checksum. Moved the checksum functionality to the end of the authservice reconciliation

@UnicornChance Did you take a stab at addressing at batching authservice updates across multiple packages?

IMO I don't think this is worth doing unless we address that scenario. I don't think we have anyone who currently using more than one sso client per Package.

I would try to debounce whatever function is actually checksuming the deployment and that would probably work.
