CHW-4518 BypassExemptionResolveBlocked

this exemption cannot be resolved yet: bypass confidence has not stayed below threshold for the required 24h window

Default message: this exemption cannot be resolved yet: bypass confidence has not stayed below threshold for the required 24h window
HTTP status: 409 (client)

Problem. POST /api/bypass/exemptions/{client_id}/resolve was refused. Cause. The client’s bypass-confidence signal has not stayed below threshold for at least 24h. The UI renders the action disabled until that becomes true; the server re-checks here so a stale UI can’t bypass the gate. Fix. Wait for the signal to remain below threshold for the full 24h window before retrying. HTTP 409.
