Refactor: separate ByomApiFlavor enum, version 1.8.3

Move BYOM discovery flavors to their own ByomApiFlavor enum instead of
mixing them into ApiFlavor. Remove embedding flavors from routing mapping
since they can't be set on embedding classes. Version bump to 1.8.3.

Tested against live BYO_AS discovery endpoint — factory correctly resolves:
- OpenAiChatCompletions → UiPathChatOpenAI
- OpenAiEmbeddings → UiPathOpenAIEmbeddings
