chore: add pre-commit hooks and flake8-bandit ruff rules

Introduce a pre-commit configuration running ruff (lint + format) and the
standard pre-commit-hooks. Expand the ruff rule set to cover flake8 (E/W/F),
flake8-django (DJ) and flake8-bandit (S); ignore S101 in tests/conftest.

Vendored static assets under web/static/ are excluded from the generic
whitespace/EOF hooks. Hand-maintained files are normalised one-off.
