Dropdowns are now in the vocabulary table header (after processing),
not in the worksheet settings (before processing). Changing a mode
automatically reprocesses all successful pages with the new settings.
Same dropdown options as the OCR pipeline grid editor.

Backend:
- _run_ocr_pipeline_for_page() now runs the full Kombi pipeline:
orientation → deskew → dewarp → content crop → dual-engine OCR
(RapidOCR + Tesseract merge) → _build_grid_core() with pipe-autocorrect,
word-gap merge, dictionary detection
- Accepts ipa_mode and syllable_mode query params on process-single-page
- Pipeline sessions are visible in admin OCR Kombi UI for debugging
Frontend (vocab-worksheet):
- New "Anzeigeoptionen" section with IPA and syllable toggles
- Settings are passed to process-single-page as query parameters

- Original pages rendered at full resolution (pdf-page-image endpoint, zoom=2.0)
instead of downscaled thumbnails
- Insert-row triangles on left margin between every row (hover to reveal)
- Dynamic extra columns: "+" button in header adds custom columns
(e.g. Aussprache, Wortart), removable via hover-x on column header
- Extra columns stored per-page (pageExtraColumns state) so different
source pages can have different column structures
- Grid template adjusts dynamically based on number of columns

- Remove max-w-7xl constraint on content area so panels stretch to edges
- Fall back to direct API thumbnail URLs when blob URLs are empty
- Original pages now reliably show even if preloaded thumbnails failed

- Swap from 3/5-2/5 grid to 1/3-2/3 flexbox (original left, table right)
- Table uses 3 equal 1fr columns for EN/DE/example instead of cramped 13-col grid
- Full viewport height minus header (calc(100vh - 240px)) for more visible rows
- Show only processed pages in original preview (filtered by selectedPages)
- Remove per-row insert buttons to reduce vertical noise
- Compact row spacing (py-1.5) to fit ~15+ rows without scrolling
