chore: add Ruff config, and update Fee Schedule total aggregration

- Update Fee Schedule total aggregation to use dict-based `get_all()` field specification for the summed `total_amount`.
- Add project Ruff configuration to `pyproject.toml` (lint selection/ignores and formatting preferences).
- Bump bench dependency `frappe` from `>=15.0.0-dev,<16.0.0-dev` to `>=16.0.0,<17.0.0`.
- Remove legacy packaging files `requirements.txt` and `setup.py`, and shift to `pyproject.toml`
