Fix pipeline consistency and smoke coverage

[leether]

Summary

• Fix pipeline import/runtime consistency issues across TTS, timeline mapping, concat duration checks, frame extraction, and narration verification.
• Route legacy animation template calls to the consolidated animation renderer and validate rule-generated animation types in CI.
• Add CI dependency install plus import/routing smoke coverage, and mark the pipeline consistency task card implemented.

Validation

• .venv/bin/python -m py_compile $(git ls-files "*.py") scripts/smoke_imports.py
• .venv/bin/python scripts/smoke_imports.py
• Offline animation render smoke for rule-backed animation types
• Offline E2E with storyboard transitions/effect concat path: timeline, concat, frame checks, harness L1/L2, and narration verification passed; narration correlations passed 6/6.

Note: the offline harness still reports the QR registry L3 check as red when the temp fixture intentionally omits a real CTA registry; that is non-blocking and did not affect L1/L2 or E2E output generation.
