revert: Disable E2EE at LiveKit level — shared key incompatible with Element Call

Browse Source 
Element Call uses per-participant keys, LiveKit Python SDK shared key mode
cannot properly decrypt. Reverting to working state (no LiveKit E2EE).
Bot still publishes keys so Element Call shows encryption indicator.
