fix: resolve Pylint errors in executor, data service, and odds call

Rename TimeoutError to PluginTimeoutError in plugin_executor.py to
avoid shadowing the built-in; no external callers affected.

Remove dead try/except in BackgroundDataService.shutdown: executor.shutdown()
never accepted a timeout kwarg so the try branch always raised TypeError.
Simplify to a direct shutdown(wait=wait) call.

Remove is_live kwarg from odds_manager.get_odds() call in sports.py;
BaseOddsManager.get_odds() has no such parameter. The live update interval
is already encoded in the update_interval_seconds argument passed alongside.
