The "conversation continuity via email" toggle was visible to all
accounts regardless of whether they had `inbound_emails` enabled.
Without inbound email infrastructure, replies to those follow-up emails
land in the agent's personal inbox instead of routing back into
Chatwoot. The feature appears to work but silently breaks the reply
path.
The toggle is now gated on the `inbound_emails` feature flag. On
self-hosted without the feature, the toggle is hidden entirely. On
cloud, it remains visible but disabled with upgrade messaging.
On the backend, `inbound_emails` is added to the manually managed
features list in `InternalAttributesService` so that Stripe webhook plan
syncs don't override it when support enables it for an account.
