feat(frontend): Add Phase Guard toggle to AutopilotPanelmakima/phaseguard-toggle

Added the phase_guard toggle to the AutopilotPanel component, which allows
users to enable/disable requiring confirmation before phase transitions.

Changes:
- Added phaseGuard and autonomousLoop fields to Contract interface in api.ts
- Added phaseGuard field to UpdateContractRequest in api.ts
- Added Phase Guard toggle UI in AutopilotPanel with similar styling to master
- Toggle shows an 'active' badge when enabled
- Connected toggle to contract update API

The toggle appears below the autopilot control buttons and allows users to
require confirmation before the supervisor advances to the next phase.
