Subject: [PATCH] test: migrate `stats/base/dists/frechet/median` to ULP-based
 assertions

Migrates from EPS-based relative tolerance assertions to
`@stdlib/assert/is-almost-same-value` ULP difference assertions. The
implementation matches the fixture expectations exactly (0 ULP) across
the full 100-case fixture set, so the fixture-loop assertion now uses
`isAlmostSameValue( y, expected[ i ], 0 )`. Applied identically to
test.native.js.

Ref: #11352
