- Lower min word length from 3→2 for hyphen-join candidates so fragments
like "ve" (from "ver-künden") are no longer skipped
- Return all spellchecker candidates instead of just top-1, so user can
pick the correct form (e.g. "stammeln" vs "stammelt")
- Frontend shows clickable alternative buttons for spell_fix suggestions
- Backend accepts text_overrides in apply endpoint for user-selected alternatives

New step "Wortkorrektur" between Grid-Review and Ground Truth that detects
and fixes words truncated or blurred at the book gutter (binding area) of
double-page scans. Uses pyspellchecker (DE+EN) for validation.
Two repair strategies:
- hyphen_join: words split across rows with missing chars (ve + künden → verkünden)
- spell_fix: garbled trailing chars from gutter blur (stammeli → stammeln)
Interactive frontend with per-suggestion accept/reject and batch controls.
