Subject: [PATCH] fix(tts): show all provider errors instead of only the last
 one

When TTS conversion fails, the error message now includes failures
from every provider in the fallback chain instead of only the last
one tried. Previously, a timeout on the primary provider (e.g.
ElevenLabs) would be masked by the final fallback's error (e.g.
"edge: disabled"), making it impossible to diagnose the real issue.

Before: "TTS conversion failed: edge: disabled"
After:  "TTS conversion failed: elevenlabs: timeout (30004ms); openai: no API key; edge: disabled"
