Michael Dieringer 1e5d901bd4 Title the article after the platform error it explains
"AL methods limited during write transactions: commit before RunModal
and Codeunit.Run" - so a developer or agent searching for the runtime
error text lands on the one article that covers all four restricted
methods. Slug and sample stems renamed to match; keywords gain the
error's own phrase and the legacy Form.RunModal name it still uses.
