fix: use full 32-bit range for phash2 in HLL estimator

:erlang.phash2/1 only returns values in [0, 2^27 - 1]. The HLL
implementation expected a 32-bit hash for its leading-zero count,
so the always-zero high bits biased estimates by ~30x past the
linear-counting cutoff. Pass an explicit 2^32 range to phash2/2
to fix the bias.

Add a regression test that validates accuracy for cardinalities
well above the linear-counting threshold (~2.5k for 1024 regs).
