fix: correct tool file path resolution to match architecture

- Updated get_tool_bas_path to look in /opt/gbo/data (source) first
- Then check botserver-stack/data/system/work (compiled) second
- Removed incorrect $HOME/data and $HOME/gb/work paths
- Fixes 'Tool file not found' error when executing inscricao tool

According to AGENTS.md architecture:
- Bots are in /opt/gbo/data primary
- They are compiled into work directory by local_file_monitor
- tool_executor was looking in wrong directories
