Disable otel (#3043)

<!-- CURSOR_SUMMARY -->
> [!NOTE]
> Disables OTEL integration for the legacy logging format and marks
session/machine IDs unused.
> 
> - **Logger (`apps/framework-cli/src/cli/logger.rs`)**:
>   - **Legacy format**:
> - Remove OTEL layer wiring even when `settings.export_to` is set (no
`otel_layer` used).
> - Mark `session_id` and `machine_id` parameters as unused
(`_session_id`, `_machine_id`).
