Add PrrSizeBytes to v1alpha2 PackageRevision status

[efiacor]

Description

• What changed: PR controller and repo controller now calculate and set status.prrSizeBytes on v1alpha2 CRDs
• Why: Users need to see package resource size without fetching content — enables client-side filtering for oversized packages
• How: Both controllers calculate size from the in-memory resource map (already loaded) and include it in their SSA status patches

Related Issue(s)

• Fixes Spike: Record pkg (PRR) size on CRD #572
• Related to Add package resource file sizes to PackageRevision interface #954 (v1alpha1 implementation)

Type of Change

• New feature
• Tests

Checklist

• Code follows project style guidelines
• Self-reviewed changes
• Tests added/updated
• Documentation added/updated
• All tests and gating checks pass

Testing Instructions

1. Deploy porch with this change
2. Create a v1alpha2 package (init, clone, or push)
3. kubectl get packagerevision <name> -o yaml — verify status.prrSizeBytes > 0
4. Push new content — verify size increases

Additional Notes

• Independent of PR Add package resource file sizes to PackageRevision interface #954 (v1alpha1 impl) — only needs the v1alpha2 type definition which is included here
• Size is calculated from in-memory resource map, no extra DB queries
• E2E covers init, clone, push, and repo discovery paths

Pull request overview

This PR adds a new status.prrSizeBytes field to the porch.kpt.dev/v1alpha2 PackageRevision API so clients can see total package resource content size without fetching PRR contents, and wires both the package revision controller and repository sync controller to populate it.

Changes:

• Added PrrSizeBytes to the v1alpha2 PackageRevisionStatus type and CRD schema.
• Populated status.prrSizeBytes from package resources in the package revision controller and repository controller sync.
• Added unit tests and extended E2E coverage to assert PrrSizeBytes is populated and updates after content changes.
