Fix TemperatureControl test flake

[cte]

Flake example: https://github.com/RooCodeInc/Roo-Code/actions/runs/15827839172/job/44612609101?pr=5044

From Roo Code:

Fixed the flaky TemperatureControl test that was failing on win32 CI by replacing hardcoded setTimeout delays with waitFor from @testing-library/react.

Problem: The test was using a fixed 100ms timeout to wait for the debounced onChange callback, but the component uses useDebounce with only a 50ms delay. On slower CI environments like win32, this timing mismatch caused intermittent failures.

Solution: Replaced the hardcoded delays with waitFor utility that polls until the expected condition is met, making the test timing-independent and more reliable across different environments.

Changes:

• Added waitFor import
• Replaced both setTimeout calls with waitFor blocks that wait for the specific expectations

The test now passes consistently and all 457 tests in the webview test suite continue to pass.
