fix: work path uses production /opt/gbo when env exists or path exists; mark .bas files indexed=true after compilation

- get_work_path_default/get_stack_path no longer rely on CWD-relative botserver-stack check which caused wrong output path in production when CI left that directory
- DriveMonitor now marks .bas file states as indexed=true after list+compile cycle
- Added compile_tool logging for work_dir path
