  1. Fix WaitLSNWakeup() fast-path check for InvalidXLogRecPtr 

    WaitLSNWakeup() incorrectly returned early when called with
InvalidXLogRecPtr (meaning "wake all waiters"), because the fast-path
check compared minWaitedLSN > 0 without validating currentLSN first.
This caused WAIT FOR LSN commands to wait indefinitely during standby
promotion until random signals woke them.

Add XLogRecPtrIsValid() check before the comparison so InvalidXLogRecPtr
bypasses the fast-path and wakes all waiters immediately.
