fix: prevent staking dashboard hang when exposure flag not cached

isPagedExposuresUsed() called storageCache.getEntry() which suspends
forever if the entry doesn't exist. The flag is only written by
ValidatorExposureUpdater (staking detail flow), so the dashboard
would hang indefinitely waiting for it.

Check cache first with isFullKeyInCache() and default to paged
exposures when the flag is absent. Also remove debug log statements.
