cursor.bulkcopy() opens a separate connection through mssql-py-core, which defaulted to a hardcoded 15s connect timeout with no way to override it. forward the cursor's query timeout (connect(timeout=X)) into pycore's connect_timeout when set, so the same limit applies to the bulk copy connection. 0 stays a no-override, leaving pycore on its default.

Summary
cursor.bulkcopy() opens a separate connection through mssql-py-core, which defaulted to a hardcoded 15s connect timeout with no way to override it from Python. I forward the cursor's query timeout (set via connect(timeout=X)) into pycore's connect_timeout when it's set, so the bulk copy connection honors the same limit. timeout=0 stays a no-override, leaving pycore on its 15s default. added tests covering the positive forward, the zero case, and that the cursor snapshot (not a later live connection change) is what's used.
