bc1804ad18 Fix vsplit side-by-side rendering: invalid TypeScript type annotation
Changed `typeof grid.zones[][]` to `GridZone[][]` which was causing
a silent build error, preventing the vsplit zone grouping logic from
being compiled into the production bundle.

45b83560fd Vertical zone split: detect divider lines and create independent sub-zones
Pages with two side-by-side vocabulary columns separated by a vertical
black line are now split into independent sub-zones before row/column
detection. Each sub-zone gets its own rows, preventing misalignment from
different heading rhythms.

- _detect_vertical_dividers(): finds pipe word_boxes at consistent x
  positions spanning >50% of zone height
- _split_zone_at_vertical_dividers(): creates left/right PageZone objects
  with layout_hint and vsplit_group metadata
- Column union skips vsplit zones (independent column sets)
- Frontend renders vsplit zones side by side via flex layout
- PageZone gets layout_hint + vsplit_group fields

e4fa634a63 Fix GridTable: show cell.text when it diverges from word_boxes
Post-processing steps like 5h (slash-IPA conversion) modify cell.text
but not individual word_boxes. The colored per-word display showed
stale word_box text instead of the corrected cell text. Now falls
back to the plain input when texts don't match.

Users can now draw rectangles on the document image in the Structure
Detection step to mark areas (e.g. header graphics, alphabet strips)
that should be excluded from OCR results during grid building.

- Backend: PUT/DELETE endpoints for exclude regions stored in structure_result
- Backend: _build_grid_core() filters all words inside user-defined exclude regions
- Frontend: Interactive rectangle drawing with visual overlay and delete buttons
- Preserve exclude regions when re-running structure detection

7a76697f95 fix: always re-run structure detection instead of using cached result
The frontend was checking for an existing structure_result and reusing
it, which meant the backend fix (passing word_boxes to graphic detection)
never had a chance to run on existing sessions.

fd79d5e4fa fix: prevent grid table overflow when union columns exceed zone bbox
When union columns from multiple content zones are applied, column
boundaries can span wider than any single zone's bbox. Using
zone.bbox_px.w as the scale reference caused the total scaled width
to exceed the container, pushing the table off-screen.

Now uses the actual total column width sum as the scale reference,
guaranteeing columns always fit within the container.

Frontend: StepCrop now handles multi_page crop responses without

Since ocr_region_paddle() now runs RapidOCR locally (same PP-OCRv5 models),
the "PaddleOCR (Hetzner)" labels were misleading. Renamed to "PP-OCRv5 (lokal)".
Removed the Kombi-Vergleich tab since both sides would produce identical results.

Replace sequential 1:1 token-to-box mapping with fuzzy text matching.
Each token from cell.text finds its best matching word_box by text
similarity (normalized prefix match + substring bonus). Handles:
- Reordered boxes (different sort between text and boxes)
- IPA corrections changing token boundaries
- Token/box count mismatches
Unmatched tokens get interpolated positions from matched neighbors.

When engine=paddle is selected, the backend overrides grid_method to
words_first and returns plain JSON (no SSE streaming). The frontend
was not aware of this override — it sent stream=true and tried to parse
SSE events from a JSON response, resulting in "Keine Daten".

Backend: _ocr_cell_crop speichert jetzt word_boxes mit exakten
Tesseract/RapidOCR Wort-Koordinaten (left, top, width, height)
im Cell-Ergebnis. Absolute Bildkoordinaten, bereits zurueckgemappt.

Frontend: Slide-Hook nutzt word_boxes direkt wenn vorhanden —
jedes Wort wird exakt an seiner OCR-Position platziert. Kein
Pixel-Scanning noetig. Fallback auf alten Slide wenn keine Boxes.

Gruppen-Sliding schob nicht weit genug nach rechts. Zurueck zum

- fontRatio=1.0 (konsistente Schriftgroesse wie Fallback)
- Token-Breiten aus medianCh * 0.7 / refFontSize (statt totalInk)

Vorher: split(/\s+/) zerlegte alles in Einzelwoerter, verlor die
Spaltenstruktur (3+ Spaces zwischen Gruppen). Woerter stauten sich links.

Jetzt: split(/\s{3,}/) erhält Gruppen wie im Cluster-Modus. Jede Gruppe
wird als Einheit von links nach rechts geschoben bis Tinte gefunden.
Breite = max(gemessene Textbreite, tatsaechliche Tintenbreite).
fontRatio=1.0, kein Wort geht verloren.

Schriftgroesse wird jetzt GLOBAL aus der medianen Zellhoehe berechnet

konsistente Groesse. Die Slide-Logik bestimmt nur noch die x-Position.

Vorher: Scale pro Zelle aus Ink-Span/Textbreite -> inkonsistente Groessen.

totalInk zaehlte nur dunkle Pixel-Spalten (Striche), ignorierte
Luecken zwischen Buchstaben. Scale war dadurch viel zu klein,
Schrift unlesbar. Jetzt wird der Ink-Span (erstes bis letztes
dunkles Pixel) als Referenz fuer die Textbreite verwendet.

Zwei wesentliche Verbesserungen:

1. Multi-group: Gruppen werden per Best-Fit-Breite den Clustern
   zugeordnet statt naiv links-nach-rechts. Damit wird z.B.
   "Kokosnuss" dem DE-Spalten-Cluster zugeordnet statt dem
   breiteren Box-Cluster.

2. Single-group Fallback: verwendet den BREITESTEN Cluster statt
   first-to-last Span. Verhindert dass Streupixel von benachbarten
   Seitenbereichen den Text nach links ziehen.

Box-Rahmen werden vom OCR als einzelne Symbole wie "|" oder ">"
erkannt und als eigene Text-Gruppen behandelt. Das verfaelscht die
Cluster-Zuordnung weil diese Artefakte entweder keinen eigenen
Cluster erzeugen oder den falschen Cluster zugewiesen bekommen.

Fix: Gruppen mit max 2 Zeichen ohne Buchstaben/Ziffern werden mit
der benachbarten Gruppe zusammengefuehrt bevor die Cluster-Zuordnung
laeuft.

statt naiv clusters[i]→groups[i] zuzuordnen. Text-Cluster sind
breiter als Rahmenlinien-Cluster.

Vorher: wenn Text mehr Wort-Gruppen hatte als Pixel-Cluster gefunden
wurden (z.B. bei Box-Rahmen die Cluster zusammenmergen), wurde die
Zelle komplett uebersprungen → Fallback bei x=0%.

Jetzt: Fallback auf Single-Span Positionierung (first→last Cluster)
statt Skip. Damit wird der Text immer korrekt horizontal platziert.

2. Sehr schmale Pixel-Cluster (< 0.5% Zellbreite) werden gefiltert,
   damit Box-Rahmen nicht als Textposition erkannt werden

Seiten mit Info-Boxen (andere Zeilenhoehe) fuehren dazu, dass _regularize_row_grid
die Zeilenpositionen verzerrt. Neuer skip_regularize Parameter nutzt stattdessen
die gap-basierten Zeilen, die der tatsaechlichen Seitengeometrie folgen.
