Fix Zhipu ASR endpoint handling

[H-Chris233]

User description

Summary

• Refs zhipu ASR: 404 due to doubled API path + errors invisible in app UI #507.
• Normalize Whisper/Zhipu ASR transcription URLs so /v4, /v4/audio, and full /v4/audio/transcriptions endpoints all post to the correct endpoint without doubling the path.
• Preserve query parameters on custom transcription endpoints.
• Fix a macOS CI-only test-server race by returning accepted test sockets to blocking mode before reading the multipart request.

Not Included

• This PR intentionally does not change Linux ASR error visibility/UI behavior.

Test Plan

• cargo test --manifest-path \"/home/chris233/openless/openless-all/app/src-tauri/Cargo.toml\" transcription_url_accepts_base_audio_or_full_endpoint -- --test-threads=1
• cargo test --manifest-path \"/home/chris233/openless/openless-all/app/src-tauri/Cargo.toml\" asr::whisper::tests::transcribe_posts_single_request_without_chunk_limit -- --test-threads=1
• git diff --check upstream/beta
