fix(columns): extend rightmost column to content right edge (right_x)

Browse Source 
Previously detect_column_geometry() ended the last column at the start
of the detected right-margin gap (left_x + right_boundary), which could
cut into actual text near the right edge of the Example column.

Since only the page margin lies to the right of the last column, the
rightmost column now always extends to right_x regardless of whether
a right-margin gap was detected. This prevents OCR crops from missing
words at the right edge of wide columns like column_example.
