Strip IPA brackets that fix_cell_phonetics may have added for short
dictionary words (e.g. "si" → "[si]") before checking if the row is
a garbled phonetic continuation. Detect phonetic text by presence of
':' (length marks), leading apostrophe (stress marks), or absence of
any word with ≥3 letters.
Fixes Row 39 ("si: [si] — So: - si:n") not being removed.
