fix(claw): handle OpenClaw TTS provider rename from "edge" to "microsoft"

OpenClaw renamed the "edge" TTS provider to "microsoft"
(openclaw/openclaw#56220). The migration tool only checked
providers.edge / tts.edge, silently finding nothing when the
source config used the new name.

Check both "edge" and "microsoft" provider keys when reading TTS
config. Normalize "microsoft" back to "edge" in the output since
Hermes still uses the original name.
