refactor(init): use API base URL for AI configuration endpoint (#41)

The /ai/generate-configuration endpoint is now served by the general
Upsun API (api.upsun.com) instead of a separate AI service host
(ai.upsun.com). Remove the separate ai_url config field and
AIServiceURL references, using the existing API base URL instead.
