## Description
Hardens the Captain model override preferences API so account-level
overrides follow the same feature-router contract used by runtime LLM
calls. The API now permits model and feature keys from `llm.yml`,
removes blank model overrides, rejects invalid saved model combinations,
and returns each feature's effective model, provider, and source for UI
clients.
Fixes https://linear.app/chatwoot/issue/CW-7425/test-new-models
## Type of change
- [ ] Bug fix (non-breaking change which fixes an issue)
- [x] New feature (non-breaking change which adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality not to work as expected)
- [ ] This change requires a documentation update
## How Has This Been Tested?
Verified the account preferences API and account model validation
behavior for valid overrides, invalid model values, unknown feature
keys, blank override removal, and effective model/provider/source
payload metadata.

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.
