chore: Convert to PEP 621 project metadata format

- Migrate pyproject.toml from Poetry-specific [tool.poetry] to standard [project] section
- Update dependencies specification to use standard requires-python and dependencies arrays
- Normalize license identifier to AGPL-3.0-only format
- Maintain all Poetry-specific configuration in [tool.poetry] for compatibility
- Update poetry.lock with latest dependency versions
