## 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.

## Bug Explanation
- The Super Admin limits form renders inputs by iterating the keys of
`account.limits`.
- When `account.limits` was present, `AccountLimitsField#to_s` returned
only that hash (no defaults).
- On save, `SuperAdmin::AccountsController` compacts the limits hash,
removing blank keys.
- Result: if only one key (e.g., `agents`) was saved, the other keys
were missing from the hash and their fields disappeared on the next
render.
## Fix
- Always start from a defaults hash of all expected limit keys and merge
in any saved overrides.
- This keeps the UI stable and ensures all limit inputs remain visible
even when the stored hash is partial.
- Upgraded meta_request to `0.8.5` to stop a dev‑only `SystemStackError`
caused by JSON‑encoding ActiveRecord::Transaction in Rails 7.2. No
production behavior changes.
## Reproduction Steps
1. In Super Admin, edit an account and set only `agents` in the limits;
leave other limit fields blank and save.
2. Re-open the same account in Super Admin.
3. Observe that only `agents` is rendered and other limit fields are
missing.
