Show console logging in vitests when the --no-silent flag is set (RooCodeInc#7467)

By default, all of the tests run in silent mode with monkey-patched the console logging so no console logging will ever appear in test output.
This confuses the agent- sometimes it will add console logging to help it debug things, and it won't see the logs that it expects.

Adds src/utils/vitest-verbosity.ts to handle verbosity resolution and console logging.
Modifies src/vitest.config.ts and webview-ui/vitest.config.ts to integrate the new verbosity control.
Removes manual console suppression from src/vitest.setup.ts and webview-ui/vitest.setup.ts as it's now handled dynamically.
