Fix ruff violations (import sort, unused imports, whitespace) in
backup_database.py, generate_website.py, meshcore_bot.py,
migrate_webviewer_db.py, packet_capture_service.py, version_info.py,
scripts/config_tui.py, scripts/update_todos.py, and validate_config.py.
Fix mypy stale type-ignore and remove unused imports in test files.
Add is_radio_zombie/is_radio_offline mock attributes to command_manager
test fixtures to prevent truthy Mock early returns.
- Add modules/config_validation.py and validate_config.py CLI to flag
non-standard section names (e.g. WebViewer -> Web_Viewer).
- Migrate JokeCommand/DadJokeCommand to Joke_Command/DadJoke_Command with
legacy [Jokes] fallback in base_command.get_config_value.
- Merge [Jokes] into [Joke_Command]/[DadJoke_Command] in config.ini.example
and add 3-line stubs for minimal-option commands.
- Add webviewer to camel_case_map; add --validate-config to meshcore_bot.py.
