Pull request overview

This PR adds channel-level controls and UI/monitoring for temporarily excluding channel–model routes when they exhibit no-permission responses or high error rates, and refactors the backend monitor to return concrete error-rate values used by retry/alert logic.

Changes:

• Move warn_error_rate / max_error_rate configuration from models to channels and surface the settings in the channel form/table plus i18n strings.
• Update the monitor implementation to return errorRate (and perform temporary exclusion based on channel settings / no-permission), including new local-cache helpers and tests.
• Improve operational behavior via TTL jitter (cache/store) and refactor request error mapping / retry selection logic.
