Commit 50b8d75e made parentheses mandatory on statement-position calls,
but kanban_app.pas was not updated, so 'PrintUsage' (a bare reference in
the --help branch) failed to parse with 'Bare reference to PrintUsage
requires () for a call'. This broke a plain 'pasbuild compile', which
reaches blaise-kanban before blaise-bif-coverage. Add the parens.
