## Context
On custom objects, clicking "+ New Tab" on a record page layout never
exposed deactivated tabs for reactivation, even though isActive: false
tabs were correctly returned by the API. Standard objects worked fine.
## Fix
isReactivatableTab gated reactivation on tab.applicationId ===
objectMetadata.applicationId. For custom objects these two ids are
intentionally different.
This check was unnecessary after all, we simply want to check if a tab
is inactive (only non-custom entities can be de-activated) 👍
