e2e: set-timout-to-session-e2e (#2782)

**Changes:**

This PR updates several end-to-end tests to improve reliability and reduce flakiness:

1. In `config.test.ts`, removed an unnecessary click action on the environment selector.
2. In `session-launcher.test.ts`, increased the timeout for session tests to 60 seconds.
3. In `test-util.ts`:
   - Added a 15-second timeout to the "App close" button click.
   - Updated the session deletion verification to use a more specific locator with a 15-second timeout.

**Rationale:**

These changes address potential timing issues in the tests, allowing for slower operations or network delays. The removal of the unnecessary click in the config test simplifies the test flow.
