Generate the OpenAPI spec on a free port (#7777)

`generateOpenApiDocs` forks a Spring Boot instance to harvest the spec,
but the scrape URL was hardcoded to `http://localhost:8080` - the app's
own port. If any Stirling instance is already listening there (a dev
server, a container, a WSL relay) the plugin reads **that** build
instead of the fork, and `task tool-models` then generates the Python
and TypeScript models from whatever happens to be running.

It fails silently and looks like success. I hit it while regenerating
models after editing Java annotations: the build passed, the compiled
class contained the new text, and the spec contained none of it.
Fetching the URL by hand settled it:

```
paths live8080: 276   ours: 276
identical parsed content: True
```

The generated `SwaggerDoc.json` was the running instance's document, not
the working tree's.

Now on a random free port, passed to both the fork and the scrape URL so
they cannot disagree. Override with `-PopenApiPort=NNNN` to use a
specific port.

+ * embedded subset fonts). What PDFium does NOT expose is the byte-encoding side of an existing font
+ * - given a PDFont and a Unicode string, what are the bytes the font's encoding produces? PDFBox
+ * does have that ({@link PDFont#encode}).
+ *
+ * <p>This endpoint accepts the source PDF + a "locator" describing where to find the font in
+ * question (page index + a sample char known to render in the target font, optionally narrowed by
+ * the font's /BaseFont name) + the Unicode text the frontend wants to encode. It returns the
+ * charcode sequence the frontend can pass to {@code FPDFText_SetCharcodes}.
+ *
+ * <p>If the locator can't find a matching text fragment, or if the font can't encode some chars,
+ * the response reports which chars are missing so the frontend can fall back to Helvetica per char.

+ *   <li>Round-trip via getFontStream / re-embed - can it rehabilitate Type3? (no - Type3 has no

+ *   <li>What fonts ship with PDFBox / fontbox? (only LiberationSans-Regular.ttf + AFM for the 14
