fix(hub): raise Docmind OSS upload timeout past httpx 3s default

SubmitDocParserJobAdvance uploads PDFs to Aliyun OSS via tea/httpx, which
defaults readTimeout to 3000ms when RuntimeOptions is empty. Multi-MB
teacher PDFs on para silo failed with ReadTimeout(3000) before the job
could start. Set connectTimeout=15s and readTimeout=5m.
