MumuTW d06d3fb67d test(sse): update three backoff assertions stale since the #8396 cooldown cap (#8539) ...

These three cases assert that a transient-error cooldown keeps doubling
to baseCooldownMs * 2^maxLevel — roughly 45.5h at the default constants.
That is precisely the blackout #8396 removed: capScaledCooldownMs
(open-sse/services/accountFallback/cooldownCap.ts) now bounds every
scaled cooldown by profile.maxCooldownMs, falling back to
BACKOFF_CONFIG.max when the profile does not configure one. All three
call checkFallbackError with a null provider, so the fallback ceiling
applies and the observed value is BACKOFF_CONFIG.max.

The backoff-level clamping each case was written to guard is unchanged
and still asserted; only the expected duration moved. The expressions
keep the original formula wrapped in the cap so the relationship stays
readable, and the first case gains a precondition assertion so it cannot
silently become vacuous if the constants change.

Fixes the error-classification (x2) and thundering-herd (x1) failures
that are red on release/v3.8.49 at its own HEAD.
