Test: replace context.TODO and context.Background to t.Context in uni…

[richie-king]

Proposed changes

Problem: Unit tests currently use context.TODO() and context.Background(), which can potentially lead to goroutine leaks and resource cleanup issues because these contexts are not automatically canceled when a test completes.

Solution: Replaced usage of context.TODO() and context.Background() with t.Context() in unit tests. This ensures that contexts are automatically canceled when tests complete and aligns the test suite with modern Go 1.24+ testing practices.

Testing: Ran all unit tests to ensure they pass with the new context handling.
Closes #3157
