Internal Report Viewer: host and use the the report viewer locally

[dfuchss]

This PR re-integrates a ReportViewer into JPlag. It allows users to launch the web-based report viewer locally by self-hosting it automatically. This feature is currently not mandatory, meaning users can choose to use it via the CLI parameter --mode. This parameter supports only running, running + viewing, as well as only viewing. In the future, this local model will become the default.

This PR thus also contributes to #1190.

Should be ready to merge after #1370

Just some comments . Probably, Docs are missing

[TwoOfTwelve]

@Kr0nox Could you please merge the develop branch into this branch? There are some conflicts in .vue files. Or should I just always accept the version from develop?

[Kr0nox]

@TwoOfTwelve it is merged

[sebinside]

Besides my two small comments (please see above), I'm fine with this PR, works great! We should merge this as soon as possible to have more than 0 days of integration testing before the 5.0 release.

When the initial and the next port are not available it prints the initial port twice

In the second message it should say 1997 is not available

Old

Sorry, I missed the sonarcloud issues. The remaining issues cannot be fixed as far as I can see.

Some minor issues below. The bigger issue is: When I package the jar and either use VIEW or RUN_AND_VIEW I end up with:

2024-02-20-12:05:59_748 [INFO] CLI - ReportViewer started on port http://localhost:1996
2024-02-20 12:05:59.899 java[52709:33325826] WARNING: Secure coding is automatically enabled for restorable state! However, not on all supported macOS versions of this application. Opt-in to secure coding explicitly by implementing NSApplicationDelegate.applicationSupportsSecureRestorableState:.

In the browser, I cannot load the page ("The connection to the server was reset while the page was loading".).

Did you make sure you compiled JPlag with -P with-report-viewer? Otherwise the report-viewer will not be bundled and exactly this error will occur. Also I think sometimes maven does not build the report-viewer for some reason, so you could try to build it manually beforehand.

Thanks, now it works! 👍

Local mode works when built as a jar. Both view only as well as run and view. What is currently not adapted is the readme (especially regarding build commands), but I will do this separately.
