Expose LLM-API service to external users

[joepavitt]

As a Node-RED Developer
I want to be able to use LLMs to quickly create flows
So that I can get to a working solution/application faster

We'd also be considering integrating FlowFuse/flowfuse#3917 here

The most complex part of this is ore likely to be scoped within FlowFuse/flowfuse#3917, but the base exposure of the API service to generate, and view, flows should be fairly simple to setup once we have FlowFuse/flowfuse#3921 up and running. We would likely want to prevent "Download" option on the flow viewer though to ensure tie in to FF?

FYI @Yndira-E @Hasmin-AC - realise I had this issue living in /flowfuse repo instead of the website. @Steve-Mcl has made great progress on getting us an alpha-version API to call (details in FlowFuse/flowfuse#3921), so once we now how we want to expose this on the website - then we're good to go
