fix: Resolve lint errors from newer ruff releases

[aronwalsh]

Summary

The qa job currently fails on every PR (e.g. #198) with 26 ruff errors. Ruff is unpinned (ruff>=0.15.21), so CI resolves the latest release each run, and recent ruff releases stabilised two rules that flag existing code:

• ISC004 (24 errors): implicit string concatenations inside the CITATIONS lists in utils/config.py. Fixed by parenthesising them (ruff auto-fix). The string values are byte-for-byte unchanged — verified by hashing CITATIONS before and after.
• PLR0917 "too many positional arguments" (2 errors in plotter.py): added to the ignore list, consistent with the other PLR09xx complexity rules (PLR0911/0912/0913/0915) already ignored.

Testing

• ruff check passes on both ruff 0.16.2 (what CI resolves today) and the locked 0.15.x
• prek run --all-files passes (all qa hooks)
• CITATIONS sha256 identical before/after

Unblocks #198.

Scope PLR0917 to plotter.py.

Line 131 adds a project-wide ignore, but the PR objective identifies only two violations in plotter.py. This can hide future violations in unrelated files. Use Ruff’s per-file ignore for plotter.py, or confirm that global suppression is intentional.

suppression only for that file and avoiding masking violations elsewhere.
