feat: implement OUI code generator for IEEE MAC address lookup

Browse source 
- Created mothership/internal/oui/gen.go with //go:generate directive
- Downloads IEEE OUI registry at generate time from standards-oui.ieee.org
- Parses OUI entries (hex format) and generates oui_data.go map
- Generated oui_data.go contains 39,195 OUI entries (>5000 required)
- Removed redundant Python generator (gen_data.py)
- Updated test cases with correct manufacturer names from IEEE registry

Acceptance criteria met:
- go generate produces non-empty oui_data.go with >5000 entries
- oui_data.go compiles without errors
- Manual trigger only (no automatic regeneration)
