Remove the separate GATEWAY_USER_ID config. The gateway now uses
IRONCLAW_OWNER_ID (config.owner_id) directly for auth identity,
bootstrap user creation, and workspace scoping.
Previously, with_owner_scope() rebinds the auth identity to owner_id
while keeping default_sender_id as the gateway user_id. This caused
a FK constraint violation when creating users because the auth
identity ("default") didn't match any user in the DB ("nearai").
Changes:
- Remove GATEWAY_USER_ID env var and gateway_user_id from settings
- Remove user_id field from GatewayConfig
- Add owner_id parameter to GatewayChannel::new()
- Remove with_owner_scope() method
- Remove default_sender_id from GatewayState
- Remove sender override logic in chat/approval handlers
- Remove debug endpoint and tracing from prior debugging
- Update all tests and E2E fixtures
