OCPEDGE-2997: Add PKI certificate inventory

[eggfoobar]

Add a deterministic role-based inventory for certificate chains and use it for existing regeneration and rotation inspection paths.

Summary by CodeRabbit

• New Features
  • Added certificate inventory capabilities with certificate paths, roles, validity details, and role-based filtering.
  • Added classification for CA, client, serving, peer, and unknown certificates.
• Bug Fixes
  • Improved certificate regeneration and rotation checks by evaluating certificate inventory entries consistently.
  • Rotation checks now reliably identify the earliest certificate requiring attention.
• Tests
  • Added coverage for inventory contents, certificate roles, validity, signer lookup, certificate retrieval, and role filtering.

Pipeline controller notification
This repo is configured to use the pipeline controller. Second-stage tests will be triggered either automatically or after lgtm label is added, depending on the repository configuration. The pipeline controller will automatically detect which contexts are required and will utilize /test Prow commands to trigger the second stage.

For optional jobs, comment /test ? to see a list of all defined jobs. To trigger manually all jobs from second stage use /pipeline required command.

Certificate inventory migration

Layer / File(s)	Summary
Inventory model and traversal pkg/util/cryptomaterial/certchains/inventory.go	Adds certificate roles, inventory entries, deterministic chain traversal, role filtering, and certificate classification.
Lifecycle checks use inventory pkg/cmd/init.go, pkg/util/cryptomaterial/certchains/certchains.go	Updates regeneration and rotation checks to iterate over inventory entries and return without traversal errors.
Inventory and regeneration validation pkg/util/cryptomaterial/certchains/inventory_test.go, pkg/cmd/init_test.go	Tests inventory ordering, roles, certificate metadata, role filtering, and the updated regeneration return value.
