Restructure the "New Document" page so users can save quickly:
- FileSectionNew becomes the first element, redesigned as a prominent
upload zone with an icon and large click target
- Title field is rendered standalone below the upload zone; it
auto-populates from the filename (via parseFilename + stripExtension
fallback) unless the user has already typed something
- All remaining metadata (who/when, description, transcription) moves
into a collapsible "Weitere Details" section that auto-expands when
URL prefill data or a form error is present, or when filename parsing
detects a date/person
- title is no longer required — the form can be saved with only a file
- DescriptionSection gains a `hideTitle` prop for use in this layout
- `form_label_title` translation key no longer carries a hardcoded `*`;
the asterisk is rendered by the template only when `titleRequired` is
set (currently only the edit form)
- E2E tests added for all three scenarios from the issue
