peter b1832afd18 style: apply ruff format across backend + scripts (line-length 100)
Mechanical, whole-tree `ruff format` pass — no behaviour change. Recorded in
.git-blame-ignore-revs (next commit) so git blame skips it.

"""Admin audit log API: read the append-only who/what/when trail, and clear it.
Admin-only. The client renders these rows in a DataTable (client-side sort/filter/paginate), so
this returns the most recent window of rows (capped) plus the true total, rather than paging
server-side — the log stays small in practice (state-changing runs + admin actions only)."""
