Feature: Form partials and the decision after a form save 

Description 

The generic pieces of the new job form of EXT:academic_jobs moved to this extension, so a later frontend form extension builds on them instead of copying them:

• The partials below Resources/Private/Partials/Academic/Form/ render the fields of an Extbase form, a text field, a text area, a select, a checkbox, a date and an upload, with their label, required mark, validation state and help text, and one alert for a form that failed validation. They are described in The form partials.
• The enum \FGTCLB\AcademicBase\Form\FlashMessageCreationMode decides whether a save queues its confirmation as a flash message. It moved here from EXT:academic_jobs, whose name for it is deprecated.
• An internal service reads the redirect page and that mode from the plugin settings, with the same settings and the same fallbacks the job form has always read.

Impact 

Nothing changes for an installation. The new job form renders the same fields from these partials, and a project override of its partials keeps applying.
