* Python: fix CopilotStudioAgent LineTooLong on large activities
Bump microsoft-agents-copilotstudio-client to >=1.2.0,<2 and forward a configurable read_bufsize (default 1 MiB) to the underlying aiohttp ClientSession via ConnectionSettings.client_session_settings. Copilot Studio streams each activity as a single SSE data line, so activities larger than aiohttp's 512 KB per-line limit previously raised aiohttp.http_exceptions.LineTooLong. Adds a client_session_settings parameter to CopilotStudioAgent and unit tests covering the default, override, and partial-settings cases.

* Python: apply read_bufsize default to supplied CopilotStudio settings
Address review feedback on the LineTooLong fix: when a user supplies their own ConnectionSettings but no client, inject the read_bufsize default so activities larger than aiohttp's 512 KB per-line limit still stream. Document configuring read_bufsize on the explicit pre-built-client path in the package and sample READMEs and the explicit-settings sample. Add unit tests covering the supplied-settings path.
