Pull request overview

This PR refactors CLARIN-DSpace’s ePIC PID integration by removing the legacy static PID service wrappers and wiring handle creation/updates through EpicHandleService inside the normal Spring-managed HandleService. It also adds support for pushing extra metadata into ePIC handle records during item install.

Changes:

• Replace the old PIDService / PIDServiceEPICv2 / DSpaceApi flow with EpicHandleService methods called directly from HandleServiceImpl.
• Add ePIC handle metadata update support and invoke it during item installation.
• Rework Spring/config wiring for the handle service implementation and add the EpicHandleField enum.

• This change comments out the only regression test for URL generation, but the replacement HandleServiceImpl.generateItemURLWithHandle() logic is still live and was moved without equivalent coverage. That leaves trailing-slash and namespace handling untested.

    /*
    @Test
    public void testGeneratingItemURL() {
        ConfigurationService configurationService = DSpaceServicesFactory.getInstance().getConfigurationService();

        //test with trailing slash
        configurationService
                .setProperty("dspace.ui.url", "http://localhost:4000/");
        String expectedUrl = "http://localhost:4000/handle/" + publicItem.getHandle();
        String pid = publicItem.getHandle();

        String url = DSpaceApi.generateItemURLWithHandle(pid, publicItem);
