+/**
+ * Adds the erasureRequests/exportRequests relation managers (see CorePlugin's
+ * Customer::erasureRequests()/exportRequests() macros) to the Customer resource's
+ * relation tabs — separate from CustomerErasureActionsExtension (headerActions)
+ * so each extension stays single-purpose. Unlike headerActions(), getRelations()
+ * genuinely is resource-keyed (called statically from the Resource class, not a
+ * page instance), so this is registered under CustomerResource::class itself in
+ * CorePlugin, not a page class.
+ *
+ * Also swaps Lunar's base UserRelationManager for Modules\Core\Privacy\
+ * RelationManagers\UserRelationManager, which adds a "Privacy Requests" row
+ * action per user — see that class's docblock for why this can't be a nested
+ * relation manager instead. Compares against Lunar's own base class, not any
+ * intermediate override, per docs/lunar.md "Overriding Lunar Relation Managers".
