fix(dataprotection): pass target metadata to post-ready jobs

[leon-ape]

Fixes #10679

Backport of #10838 to release-1.1.

The automatic cherry-pick conflicted only in controllers/dataprotection/restore_controller_test.go. The resolution preserves release-1.1's existing Cluster cleanup behavior and adds cleanup for the Component fixture introduced by the backport.

Validation:

• pkg/dataprotection/restore: PASS
• controllers/dataprotection post-ready context: PASS
• controllers/dataprotection full suite: PASS
• make lint: PASS
• git diff --check: PASS
