webui: address review feedback from allozaur

Normalized streamed model names during chat updates
by trimming input and removing directory components before saving
or persisting them, so the conversation UI shows only the filename

Forced model names within the chat form selector dropdown to render as
a single-line, truncated entry with a tooltip revealing the full name
