The host list on the compliance page showed stale resolution date and
remediation plan values after editing them in the detail sidebar, until
an unrelated refresh (filter, team, or tab change) ran. handleSaveMetadata
re-fetched only the panel's own detail and never notified the parent.
Add an onMetadataSaved callback invoked after a successful metadata PATCH
and wire it to the existing list refresh in CompliancePage, mirroring the
onNoteAdded pattern. The list now reflects saved changes immediately.
