style: align oxfmt to trailing-comma 'all' and normalize code

The repo was authored prettier-style (trailing-comma 'all') but .oxfmtrc.json
was set to 'es5', so every formatted file diverged. Switch the config to 'all'
to match the existing code, ignore docs/** and **/drizzle/** (prose + generated
snapshots the formatter should not own), and reformat the source tree once for
consistency. No behavioural change; all suites green (api 60, worker 28, admin 21).
