test(pools): update metadata URL length for 128-char limit

Increase the minimum generated metadata URL length in the negative pool
registration test to 129 characters, reflecting the new 128-character
limit (was 64). Update assertions and error message checks accordingly.
Also increase hypothesis max_examples for broader coverage. Retain
backward compatibility for cardano-node <= 10.6.0 by checking for the
old error message.
