Fix commit job and OCR text editing

- OCR text is now shown in an editable textarea (plain_ocr mode) so
  users can correct it before committing
- editedOcrText state tracks edits; commit job sends the edited value
  instead of the original result.text
- Remove silent early-return guard that blocked commit when text was empty
- Copy and download also use the edited text
