fix(discord): pass hydrated config to ack reactions to fix SecretRef resolution

When extracting `reactMessageDiscord`, it defaulted to reading the raw config (which contains `SecretRef`s) if a hydrated `cfg` was omitted. We now pass the pre-resolved `cfg` context into the reaction options so the plugin SDK resolves the token via memory rather than the raw file.
