Merge pull request 'style(plausible): ruff format the rewritten event-tracking fixture' (#18) from fix/plausible-format into main

Self-inflicted: the rewrite in eecc4aa left the file unformatted, which the push
lint gate flags. Formatting only - no behaviour change.

(Note for the operator: the gate is red on main for unrelated reasons - 90 other
files also fail ruff format, and tests/unit/test_f211_sso_skip.py fails ruff
check C420. Neither is touched here; both predate this branch.)
