Drop Python 3.8/3.9, add 3.12-3.14, bump all dependencies and hooks (#400)

Python 3.8 (EOL Oct 2024) and 3.9 (EOL Oct 2025) are no longer
supported. This unblocks bumping to latest package versions.

Runtime: Click 8.1.7→8.3.1, pytz 2024.1→2026.1.post1,
PyYAML 6.0.1→6.0.3, requests 2.32.3→2.33.0, tabulate 0.9.0→0.10.0

Dev: mypy 1.10.1→1.19.1, pre-commit 3.3.3→4.5.1, pylint 3.2.5→4.0.5

Pre-commit hooks: autopep8 (switched from mirrors-autopep8 v1.5.1 to
hhatto/autopep8 v2.3.2 for Python 3.13+ compat), pre-commit-hooks
v2.5.0→v6.0.0, flake8 3.9.2→7.3.0, pyupgrade v1.27.0→v3.21.2,
mirrors-isort v4.3.21→v5.10.1.

Removed deprecated seed-isort-config and fix-encoding-pragma hooks.
Renamed check-byte-order-marker to fix-byte-order-marker (v6 rename).
Updated Dockerfile base from python:3.8 to python:3.13.
