chore(style): repo-wide prettier sweep before v1.4.6 tag

Long-overdue prettier sweep; prettier had drifted vs. checked-in code
across ~130 files (mostly long-argument line-break wrapping in TS and
table-padding in markdown). Pure formatting — no semantic changes —
and required to clear the v1.4.6 release gate's `pnpm format:check`.
