> NIFI-16226 corrected Parameter Context updates when adding provider-backed inheritance in a cluster. Additional system-test coverage should protect two adjacent Parameter update behaviors exercised by the same effective-Parameter enrichment path.
> The tests should verify:
> * Deleting a local Parameter that overrides an inherited Parameter removes the local definition and reveals the inherited value.
> * Updating a locally referenced Parameter preserves the referencing Parameter's raw expression, such as `#\{X}`, instead of persisting its resolved value.
> Both scenarios should run through `ParameterContextIT`, which also causes them to run in clustered mode through `ClusteredParameterContextIT`.
> Acceptance Criteria:
> * A child Parameter Context defines a local Parameter with the same name as a Parameter inherited from its parent.
> * Deleting the local override leaves no local definition and exposes the inherited parent value in the effective view.
> * Updating `X` in a context containing `Y = #\{X}` persists the new value of `X` while retaining the raw `#\{X}` value for `Y`.
> * The tests pass in standalone and clustered system-test configurations.
> * No production-code changes or new dependencies are required.
