refactor(test): drop 'as unknown as' on tableState via V5 literal

Construct PlDataTableStateV2Normalized v5 directly instead of running
createPlDataTableStateV2() (catalog SDK 1.77.0, emits v7) through an
'as unknown as' cast to satisfy mixcr-clonotyping-2's pin on SDK 1.63.1
(v5). The v5 shape is small and stable; literal-with-type-annotation
keeps full type-checking with no escape hatches.

Drops the now-unused createPlDataTableStateV2 import from helpers.ts.
