add: SQLite-backed structured logging with retention

Replace JSON/file logging with a logs.db (WAL) store. Thread the logger
through the encoder and metadata client for debug instrumentation of every
ffmpeg/ffprobe/opusenc invocation and OMDb/TVmaze request. API keys are
redacted before request URLs are logged. Retention defaults to 7 days,
overridable via log_retention_days in config.
