feat(brain): Company Brain Models settings tab

[MaheshtheDev]

Adds an admin-gated Models tab (main/triage/research pickers) that reads/writes the mono /brain/models endpoint, shown only for Company Brain orgs. Extracts a shared useOrgMemberRole hook so the brain settings sections dedupe the getActiveMember call.

Fixes ENG-1054

Summary: Reviewed the Company Brain Models settings tab implementation. The code is clean with no bugs or security issues found. The shared useOrgMemberRole hook properly deduplicates API calls, auth is handled correctly with credentials: "include", and admin gating is properly enforced both on the UI and via the backend 403 handling.

Score: 10/10 — Ready to ship.

Overview: Adds an admin-gated Models settings tab for Company Brain orgs and extracts a shared useOrgMemberRole hook to dedupe role-checking across the company-brain settings components.

Issues found: None — this looks good to ship.

Details:

• The useOrgMemberRole hook correctly guards the query with enabled && !!org?.id and returns consistent role/isAdmin values matching the original inline implementations
• The useBrainModels and useUpdateBrainModels hooks properly use credentials: "include" for auth, handle errors appropriately, and invalidate the cache on successful mutation
• The Models component correctly guards rendering with !isCompanyBrain early return and disables controls for non-admins
• The dirty check and save button logic are correctly synchronized — the button is disabled when no changes exist, preventing empty PATCH requests
• The nav filtering in settings-content.tsx properly shows/hides the Models tab based on Company Brain status

Score: 10/10
