Wire DeepL API as the cloud translation backend for Paid tier users.

Requirements:

Translate tone labels (not transcription text — labels are short, low-PII, ~5–15 words)
Language auto-detection from STT output locale
Manual language override in settings
DeepL Free API as BYOK path (see issue #1 for BYOK wizard)
DeepL Pro API as CF-managed Paid path
Rate limiting: translate only on ToneEvent emit, not on every ring buffer frame
Cache translated labels for the session (same label translated once per session)
