loadGrid depended on buildGrid (for 404 fallback), which depended on
ipaMode/syllableMode. Every mode change created a new loadGrid ref,
triggering StepGridReview's useEffect to load the OLD saved grid,
overwriting the freshly rebuilt one.
Now loadGrid only depends on sessionId. The 404 fallback builds inline
with current modes. Mode changes are handled exclusively by the
separate rebuild useEffect.

The old guard checked if grid was loaded AND set initialLoadDone in
the same pass, then returned without rebuilding. This meant the first
user-triggered mode change was always swallowed.
Simplified to a mount-skip ref: skip exactly the first useEffect trigger
(component mount), rebuild on every subsequent trigger (user changes).

The useEffect for mode changes called buildGrid() which was a
useCallback closing over stale ipaMode/syllableMode values due to
React's asynchronous state batching. The first click triggered a
rebuild with the OLD mode; only the second click used the new one.
Now inlines the API call directly in the useEffect, reading ipaMode
and syllableMode from the effect's closure which always has the
current values.

Hybrid approach mirroring English IPA:
- Primary: wiki-pronunciation-dict (636k entries, CC-BY-SA, Wiktionary)
- Fallback: epitran rule-based G2P (MIT license)
IPA modes now use language-appropriate dictionaries:
- auto/en: English IPA (Britfone + eng_to_ipa)
- de: German IPA (wiki-pronunciation-dict + epitran)
- all: EN column gets English IPA, other columns get German IPA
- none: disabled
Frontend shows CC-BY-SA attribution when German IPA is active.

Our IPA system only has English dictionaries (Britfone MIT, eng_to_ipa
MIT). The "IPA: nur DE" option was useless at best and misleading.
Removed from dropdown, type definition, and API validation.
Syllable DE mode stays — pyphen has a German hyphenation dictionary.

The dropdowns only updated state but didn't trigger buildGrid().
Now a useEffect watches ipaMode/syllableMode and rebuilds
automatically (skipping the initial mount).

Extend ipa_mode and syllable_mode toggles with language options:
- auto: smart detection (default)
- en: only English headword column
- de: only German definition columns
- all: all content columns
- none: skip entirely
Also improve English column auto-detection: use garbled IPA patterns
(apostrophes, colons) in addition to bracket patterns. This correctly
identifies English dictionary pages where OCR produces garbled ASCII
instead of bracket IPA.

Backend: Remove en_col_type fallback heuristic (longest avg text) that
incorrectly identified German columns as English. IPA now only applied
when OCR bracket patterns are actually found. Add ipa_mode (auto/all/none)
and syllable_mode (auto/all/none) query params to build-grid API.
Frontend: Add IPA and Silben dropdown selects to GridToolbar. Modes
are passed as query params on rebuild. Auto = current smart detection,
All = force for all words, Aus = skip entirely.

Users can now right-click any cell to set text color (red, green, blue,
orange, purple, black) or remove the color bar without changing text.
A "reset" option restores the OCR-detected color. This enables accurate
Ground Truth marking when OCR assigns colors to wrong cells.

- Color bar (red/colored indicator) now only shows when word_boxes
text still matches the cell text — editing the cell hides stale colors
- New "Auto-Korrektur" button: detects dominant prefix+number patterns
per column (e.g. p.70, p.71) and completes partial entries (.65 → p.65)
— requires 3+ matching entries before correcting

- 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 document category "Woerterbuch" (frontend type + backend validation)
- Column delete: hover column header → red "x" button (with confirmation)
- Column add: hover column header → "+" button inserts after that column
- Both operations support undo/redo, update cell IDs and summary
- Available in both GridEditor and StepGridReview (Kombi last step)

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.
