Reject live mode for table workflow tools

[icecrasher321]

Summary

• Reject legacy deploymentMode live calls for add_workflow_group and update_workflow_group at the Copilot table-tool boundary.
• Return an actionable error explaining that table workflow groups use the latest active deployment.
• Keep the public table HTTP contracts unchanged.

This closes the rolling-version case where an older Mothership could request draft semantics and Sim would silently report success while actually using deployed state.

Greptile Summary

This PR rejects legacy deploymentMode: "live" requests for Copilot table workflow-group creation and updates, preventing callers from receiving success after their requested semantics are silently changed.

• Adds an early, actionable rejection before workflow resolution or mutation.
• Adds parameterized coverage for both add_workflow_group and update_workflow_group.
• Leaves the public table HTTP contracts unchanged.

Confidence Score: 5/5

The PR appears safe to merge, with the intended legacy live-mode requests rejected before any workflow resolution or table mutation.

The new condition matches the documented legacy payload, returns an actionable failure, and tests both affected workflow-group operations while confirming mutation is not invoked.

Important Files Changed

Filename	Overview
apps/sim/lib/copilot/tools/server/table/user-table.ts	Adds a narrowly scoped pre-mutation guard for legacy live-mode workflow-group requests; no actionable defect identified.
apps/sim/lib/copilot/tools/server/table/user-table.test.ts	Replaces silent-stripping coverage with explicit rejection assertions for both affected operations and verifies no resolution or creation occurs.

Closing per rollout decision: Mothership will deploy alongside Sim, so we do not need special handling for stale deploymentMode calls.
