Update tools.func

- Add _TOOLS_FUNC_LOADED guard to prevent double-sourcing
- Remove duplicate is_alpine() (core.func version is more robust)
- Fix end_timer: now actually outputs duration (was silent)
- Fix SQL injection in setup_mariadb_db: escape single quotes in identifiers
- Fix SQL injection in setup_postgresql_db: escape single quotes in identifiers
- Fix sed injection in edit_yaml_config: escape | and & in value
- Fix command injection in curl_with_retry: use array instead of string eval
- Fix command injection in curl_api_with_retry: use array instead of string eval
