- Add ContextVarsMiddleware for automatic user_id/chat_id/username binding via structlog contextvars (aiogram) and http_method/http_path (FastAPI) - Use bound_contextvars() context manager instead of clear_contextvars() to safely restore previous state instead of wiping all context - Register ContextVarsMiddleware as outermost middleware (before GlobalError) so all error logs include user context - Replace structlog.get_logger() with structlog.get_logger(__name__) across 270 calls in 265 files for meaningful logger names - Switch wrapper_class from BoundLogger to make_filtering_bound_logger() for pre-processor level filtering (performance optimization) - Migrate 1411 %-style positional arg logger calls to structlog kwargs style across 161 files via AST script - Migrate log_rotation_service.py from stdlib logging to structlog - Add payment module prefixes to TelegramNotifierProcessor.IGNORED_LOGGER_PREFIXES and ExcludePaymentFilter.PAYMENT_MODULES to prevent payment data leaking to Telegram notifications and general log files - Fix LoggingMiddleware: add from_user null-safety for channel posts, switch time.time() to time.monotonic() for duration measurement - Remove duplicate logger assignments in purchase.py, config.py, inline.py, and admin/payments.py
