fix(export): copyright/blank slides, bundle-relative media, probundle injection, song links

- populate COPYRIGHT (title/author/copyright/CCLI) + blank slides on every song; songHasContent ignores locked sections
- foreground info/moderation images now bundle-relative (fixes blank images)
- pre-added .probundle injection: Zip64-fix + verbatim .pro extraction (fixes empty bundle)
- nametag subtitle split (text + subtitle); smaller non-bold render
- skip songs with no content slides at export with German warning
- link service agenda songs to SongDB edit modal via #song-<id>
- allow CCLI import of metadata-only songs (no lyric sections)
- expose has_content_slides on service songs; show "Keine Inhaltsfolien"
