Page-split sub-sessions (current_step=2) had orientation marked as skipped
but uiStep remained at 0 (orientation step), causing StepOrientation to
render for a sub-session that has no orientation data. Now advances to
uiStep=1 (deskew) when orientation is skipped.

The reset useEffects in StepOrientation/Deskew/Dewarp/Crop were clearing
orientationResult when sessionId changed (e.g. during handleOrientationComplete),
causing the right side of ImageCompareView to show nothing. Using key={sessionId}
on the step components instead forces React to remount with fresh state when
switching sessions, without interfering with the upload/orientation flow.

The page-split detection was only implemented in the regular pipeline
page but not in the OCR Overlay page where the user actually tests
with Kombi mode. Now the overlay page has full sub-session support:
- openSession: handles sub_sessions, parent_session_id, skip logic
for page-split vs crop-based sub-sessions, preserves current mode
- handleOrientationComplete: async, fetches API to detect sub-sessions
- BoxSessionTabs: shown between stepper and step content
- handleNext: returns to parent after sub-session completion
- handleSessionChange/handleBoxSessionsCreated: session switching

- New ImageLayoutEditor: SVG overlay on original scan with draggable
column dividers, horizontal guidelines (margins/header/footer),
double-click to add columns, x-button to delete
- GridTable: MIN_COL_WIDTH 40→80px for better readability
- Arrow up/down keys navigate between rows in the grid editor
- Ctrl+Click for multi-cell selection, Ctrl+B to toggle bold on selection
- getAdjacentCell works for cells that don't exist yet (new rows/cols)
- deleteColumn now merges x-boundaries correctly
- Session restore fix: grid_editor_result/structure_result in session GET
- Footer row 3-state cycle, auto-create cells for empty footer rows
- Grid save/build/GT-mark now advance current_step=11

- New StepGridReview component: split-view (scan image left, grid right),
confidence stats, row-accept buttons, zoom controls
- Kombi Pipeline case 6 now uses StepGridReview instead of plain GridEditor
- Kombi step label changed to "Review & GT"
- Ground Truth queue page simplified to overview/navigation only
(links to Kombi pipeline for actual review work)
- Deep-link support: /ai/ocr-overlay?session=xxx&mode=kombi

- Ground Truth button on last step of Pipeline/Kombi modes in ocr-overlay
- Prominent category picker in active session info bar (pulses when unset)
- GT badge shown when session has ground truth reference
- Backend: auto-detect pipeline from ocr_engine, store in GT snapshot
- Pipeline info shown in GT session list and regression reports
- Also pass pipeline param from ocr-pipeline StepGroundTruth

Graphic detection needs word positions to exclude text from the ink mask.
Previously Struktur ran before OCR, causing every word to be detected as
a graphic element. Now:
- Pipeline: Struktur at index 7 (after Wörter)
- Kombi: Struktur at index 5 (after PP-OCRv5+Tesseract, before Tabelle)
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Insert the Struktur detection step between Zuschneiden and
PP-OCRv5+Tesseract in the Kombi pipeline on /ai/ocr-overlay.

Backend: new grid_editor_api.py with build-grid endpoint that detects
bordered boxes, splits page into zones, clusters columns/rows per zone
from Kombi word positions. New DB column grid_editor_result JSONB.
Frontend: GridEditor component with editable HTML tables per zone,
column bold toggle, header row toggle, undo/redo, keyboard navigation
(Tab/Enter/Arrow), image overlay verification, and save/load.

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.

Add /rapid-kombi backend endpoint using local RapidOCR + Tesseract merge,
KombiCompareStep component for parallel execution and side-by-side overlay,
and wordResultOverride prop on OverlayReconstruction for direct data injection.

Runs both OCR engines on the preprocessed image and merges results:
word boxes matched by IoU, coordinates averaged by confidence weight.
Unmatched Tesseract words (bullets, symbols) are added for better coverage.

Uses the cropped/dewarped image instead of the original so the overlay
shows the correctly oriented page. 5 steps instead of 2.

New 2-step mode (Upload → PaddleOCR+Overlay) alongside the existing
7-step pipeline. Backend endpoint runs PaddleOCR on the original image
and clusters words into rows/cells directly. Frontend adds a mode
toggle and PaddleDirectStep component.

_heal_row_gaps verschiebt Zell-Positionen nach Entfernung von Artefakt-Zeilen,
was im Overlay zu sichtbarem Versatz fuehrt (z.B. 23px bei "badge").
Neuer skip_heal_gaps Parameter in build_cell_grid_v2 und words-Endpoint
behaelt die exakten Zeilen-Positionen bei.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
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.
