feat(tenant): per-tenant brand and question limit overrides

Add nullable brand_limit / question_limit columns on tenants so ops
admins can override the plan-derived brand-library quotas per account.
When set, these take precedence over config.yml plan defaults across the
brand-library summary, question materialization, and the daily
monitoring worker's primary-client plan resolution.

Ops side exposes them on admin-user create plus a new
PUT /admin-users/:id/limits endpoint, invalidating the brand-library
summary cache on change. The ops-web AdminUsers view gains matching
inputs on the create and edit modals.
