fix(backend): defer provider endpoint/header resolution to call time

Browse source 
The provider previously evaluated env.AI_BASE_URL at module load, which
threw when AI is disabled (no URL configured). Compute the endpoint and
Authorization header lazily inside the fetch calls so importing the module
never fails; the runtime and triage layers already gate on AI_ENABLED first.
