AI PDF creation ("create a PDF for me") has been broken since the
Policies backend (#6527) introduced PolicyExecutor as the tool execution
pipeline. PolicyExecutor runs normal single-input tools with a per-file
loop, but generator tools like `create-pdf-from-html-agent` take no
input file and build their output purely from parameters. With zero
input files the loop ran zero times, so the endpoint was never called
and the step silently produced nothing. The chat reported success
("Created Purchase Order") while no document ever appeared.
This adds an `else if (inputFiles.isEmpty())` branch so a generator tool
is called once with an empty file list, matching what the multi-input
branch already does for an empty input. Two files changed: the
one-line-ish fix in `PolicyExecutor`, and a regression test covering the
no-input case.
