test(solid): deterministic clock in client-recovery-record.spec.ts (#3635)

The "already rejected at hydration" case asserted `waitedMs < 5` on the
wall clock. `waitedMs` is the delta between two `performance.now()`
reads in the runtime — at boundary registration and when the queued
`recover` microtask runs — and on a loaded, coverage-instrumented CI
worker that hop read 5.3ms, 7.3ms and 13.3ms today. A failed assertion
also skipped the test's own `off()`, leaking the listener into the next
test, whose `observed("recovery") === false` check then failed too.

`performance.now()` is now a scripted clock (the #3598 pattern): it
stands still unless the test moves it, so every duration is asserted
exactly — `waitedMs: 0` for the already-rejected case, `30` for the
streaming case where the test advances the clock before rejecting, and
`renderMs: 2` because rendering the children advances it by 2. The
subscription is torn down in `afterEach`, so a failure cannot cascade.
