Hybrid approach mirroring English IPA:
- Primary: wiki-pronunciation-dict (636k entries, CC-BY-SA, Wiktionary)
- Fallback: epitran rule-based G2P (MIT license)
IPA modes now use language-appropriate dictionaries:
- auto/en: English IPA (Britfone + eng_to_ipa)
- de: German IPA (wiki-pronunciation-dict + epitran)
- all: EN column gets English IPA, other columns get German IPA
- none: disabled
Frontend shows CC-BY-SA attribution when German IPA is active.

OCR engines don't detect | pipe chars used as syllable dividers in
dictionaries. After dictionary detection (is_dict=True), use pyphen
(MIT) to insert syllable breaks into headword cells. Tries DE first,
then EN. Skips IPA content, short words, and cells already containing |.
Also adds pyphen>=0.16.0 to requirements.txt.

- Add pyspellchecker (MIT) to requirements for EN+DE dictionary lookup
- New spell_review_entries_sync() + spell_review_entries_streaming():
- Dictionary-backed substitution: checks if corrected word is known
- Structural rule: digit at pos 0 + lowercase rest → most likely letter
(e.g. "8en"→"Ben", "8uch"→"Buch", "5ee"→"See", "6eld"→"Geld")
- Pattern rule: "|." → "1." for numbered list prefixes
- Standalone "|" → "I" (capital I)
- IPA entries still protected via existing _entry_needs_review filter
- Headings/untranslated words (e.g. "Story") are untouched (no susp. chars)
- llm_review_entries + llm_review_entries_streaming: route via REVIEW_ENGINE
env var ("spell" default, "llm" to restore previous behaviour)
- docker-compose.yml: REVIEW_ENGINE=${REVIEW_ENGINE:-spell}
- LLM code preserved for fallback (set REVIEW_ENGINE=llm in .env)
