fix(tts): fall back to raw provider imports

[LeonSGP43]

Summary

• keep Edge TTS and ElevenLabs imports usable when lazy_deps auto-install fails
• log the lazy-install failure at debug level and still attempt the raw provider import
• add regression tests for PYTHONPATH-style provider installs that bypass the venv

Testing

• uv run --extra dev python -m pytest tests/tools/test_tts_lazy_import_fallback.py
• uv run --extra dev ruff check tools/tts_tool.py tests/tools/test_tts_lazy_import_fallback.py

Duplicate of #53289 (earliest-open canonical fix for #53259). Same mechanism — replace raise ImportError(str(e)) with a debug log + fall-through to the raw import in the TTS _import_* helpers. #53289 is broader (also covers _import_mistral_client); this PR covers edge + elevenlabs only.

Code Review Summary

Verdict: Approved

Changes TTS import functions to fall back to raw imports when lazy_deps.ensure() fails (e.g. read-only venv). Clean fix with two dedicated tests covering edge_tts and elevenlabs fallback paths.

Thanks for the focused fallback fix. The reported Edge and ElevenLabs failure paths are still present on current main at tools/tts_tool.py:93-95 and tools/tts_tool.py:114-116, and this diff reaches the existing raw imports after a lazy-install failure.

Problems

• The equivalent Mistral TTS path remains unaddressed: tools/tts_tool.py:132-140 raises on a non-ImportError from ensure("tts.mistral") before the raw mistralai import. The linked canonical duplicate fix(tts): fall back to raw imports after lazy install failure #53289 includes this sibling helper.

Suggested changes

• Extend this fallback and its regression coverage to _import_mistral_client() so all three lazy-installed TTS SDK paths behave consistently.

The lazy-install recovery gap was fixed in #73510 via @tusharui's #67314 (raw-import fallback when lazy_deps.ensure fails). Thanks for the contribution!

(Landed via #73510, merge c0c5dac531.) Closing.
