fix: wire DigestConfig through SDK and system for end-to-end digest

- Inject DigestConfig (persona, sections, TTS backend, voice_id) into
  MorningDigestAgent from both JarvisSystem._run_agent and Jarvis SDK
- Always inject digest_collect + text_to_speech tools for digest agent
- Fix TTS tool: import speech backends before checking TTSRegistry
- Fix Cartesia: default to British Butler voice when voice_id is empty
- Fix DigestStore: allow cross-thread SQLite access for FastAPI
- Propagate agent metadata (audio_path) through system return dict
- Add music section to default source map in MorningDigestAgent

Tested end-to-end: Qwen3.5 9B (Ollama) + Cartesia TTS + real data
from Oura, Gmail, Calendar, Tasks, Spotify, Apple Music.
