feat(tests): enhance test_querybot with stream target and input val…

…idations

- Add minimum size constraints to `dummy_text` and `mock_response` in `test_querybot` to ensure more realistic test data.
- Introduce `stream_target` parameter to `QueryBot` instantiation within `test_querybot`, allowing tests to specify output stream (either "panel" or "stdout").
- Rename `test_querybot_init` to `test_querybot` to better reflect the test's purpose, which now includes sending a query to the bot.
- Execute a sample query against the `QueryBot` instance to verify its operational status post-initialization.

This enhancement aims to improve the robustness and coverage of `QueryBot` testing by ensuring the presence of meaningful test data and by testing a broader spectrum of the bot's functionality.
