chore(platform): drop dashboard.cozystack.io CRDs via migration 40

Existing clusters still have the legacy dashboard.cozystack.io CRDs
installed even after the dashboard controller has been removed.
Add a platform migration that deletes them and bump targetVersion
to 41.

+# Migration 40 --> 41

+# controller, which is no longer part of Cozystack.
+#
+# The dashboard controller used to project ApplicationDefinitions into a set
+# of dashboard.cozystack.io CRs (Sidebar, Factory, Navigation, Breadcrumb,
+# CustomFormsOverride, CustomFormsPrefill, CustomColumnsOverride,
+# MarketplacePanel, TableUriMapping, CFOMapping, BreadcrumbInside) consumed
+# by the legacy UI. cozystack-ui now reads ApplicationDefinitions directly,
+# so both the controller and the CRDs are dead. The chart no longer ships
+# these CRDs, but existing clusters still have them installed — delete them
+# explicitly here so they do not stay around as orphans.
