Merge bitcoin/bitcoin#27786: fuzz: fix wallet notifications.cpp

a10f032 fuzz: fix wallet notifications.cpp (furszy)

Pull request description:

  Fixing bitcoin/bitcoin#27469 (comment).

  As the fuzzing test requires all blocks to be scanned by the wallet
  (because it is asserting the wallet balance at the end), we need to
  ensure that no blocks are skipped by the recently added wallet
  birth time functionality.

  This just means setting the chain accumulated time to the maximum
  value, so the wallet birth time is always below it, and the block is
  always processed by the wallet.
