test(engine): give the 150-track audio mix test a Windows-sized budget (#3587)

Browse Source 
The ENAMETOOLONG regression writes 150 real clip files and the mixer
existence-checks each one: ~58ms on Linux, but past vitest's 5s default on
the Windows lane. packages/engine sets no global testTimeout, so heavy
tests here carry an explicit one.

On timeout its abandoned async work kept calling the shared runFfmpegMock
after afterEach cleared it, so the next test saw 5 calls instead of 3 and
lost its queued once-implementations to the leak. mockReset stops an
aborted test from handing leftovers to the next one.
