Support using existing OpenRouter/KiloCode key for Morph when not using OR/KC as main model

I am using Gemini CLI/Qwen Coder as main coding model. But I'm not sure will it enable morph fast apply with existing providers(OR/KC).
Since morph fast apply dashboard does not have a place for personal api payments. But it's accessable on OpenRouter, so it's ok to has seperate provider settings for Morph

in the morph dashboard you can set a billing method: https://morphllm.com/dashboard/billing
