ruff.toml has declared `quote-style = "single"` and line-length 120 since the
lint job landed, and 118 of 128 files follow it. The panel backend and the
netbox configuration were written in black/prettier style instead, so a
`ruff format --check` would have failed on them from the start.
Bring them onto the style the repository already declares, which is what makes
the check adoptable at all. Formatting only: apart from quote style the diff is
multi-line expressions joined where they fit inside 120 columns.
Both suites still pass afterwards (25 pytest, and ruff check is clean).
