Susana Ferreira f5858c8a18 fix: unregister metrics on reconciler stop to prevent panic on restart (#21647) ...

## Description

Fixes a panic that occurs when the prebuilds feature is toggled by
adding/removing a license. The `StoreReconciler` was not unregistering
the `reconciliationDuration` histogram, causing a "duplicate metrics
collector registration attempted" panic when a new reconciler was
created.

## Changes

* Unregister the `reconciliationDuration` histogram in `Stop()`
alongside the existing metrics collector
* Change log level when stopping the reconciler with a cause, since
"entitlements change" is not an error condition
* Add `TestReconcilerLifecycle` to verify the reconciler can be stopped
and recreated with the same prometheus registry
