Add exponential backoff retry to all downstream calls

New controller/retry.js wraps async calls with infinite retries, capped

at 30s with jitter. Applied to: TPB search, TMDB, Emby, Ollama chat,

Transmission RPC, and the status/status interval calls inherit it via

a Proxy around the Transmission client.

Also handles ollama package returning pre-parsed JSON objects.
