test(translate): add 27 tests for dict hash + classify/persist

test_dict_snapshot_hash.py (10 tests):
- Hash changes when entry added/modified/removed
- Hash changes when second dictionary linked
- Hash deterministic for same state
- Hash stable when non-dict data changes
- Both orchestrator and preview implementations produce same hash
- Multiple entries — tracks latest update

test_batch_classify_persist.py (17 tests):
_Classify (11 tests):
- Same-lang partial no cache → LLM
- Same-lang partial with cache → pre_rows
- Same-lang all match → short-circuit
- Und/empty detected → normal flow
- Cache all targets → pre_rows
- Cache partial → LLM (missing lang)
- Approved translation → pre_rows
- Preview edits cache → pre_rows
- Mixed batch routing
- FR source + [fr, en, de] + cache {fr, en} → LLM (de missing)

_Persist_pre (6 tests):
- Same-lang creates TL for source only
- Cache-hit creates TL for each target
- Same-lang + cache: matching uses source_text, others use cache
- No cache + no approved → skip non-source (no empty TL)
- Approved translation fallback
- Multiple pre_rows processing
