Benjamin Admin be86a7d14d fix: preserve pipe syllable dividers + detect alphabet sidebar columns ...

1. Pipe divider fix: Changed OCR char-confusion regex so | between
   letters (Ka|me|rad) is NOT converted to I. Only standalone/
   word-boundary pipes are converted (|ch → Ich, | want → I want).

2. Alphabet sidebar detection improvements:
   - _filter_decorative_margin() now considers 2-char words (OCR reads
     "Aa", "Bb" from sidebars), lowered min strip from 8→6
   - _filter_border_strip_words() lowered decorative threshold from 50%→45%
   - New step 4f: grid-level thin-edge-column filter as safety net —
     removes edge columns with <35% fill rate and >60% short text
