Reject invalid or zero-quality language entries.

Number.parseFloat accepts prefixes such as 0.5junk, and the filter keeps finite values outside the valid q-value range, including 0. A request such as fr;q=0,ja;q=0 can therefore select fr instead of falling back, and ja;q=2 can outrank valid preferences. Parse a strict q-value and keep only 0 < q <= 1.

In `@apps/marketing/src/app/i18n-server.ts` around lines 19 - 22, Update the
language-entry parsing around the quality value and filter so q-values are
accepted only when the entire value is a valid numeric representation, rejecting
prefixed or malformed values. Keep only finite qualities where 0 < quality <= 1,
excluding zero and out-of-range values while preserving valid language tags and
preferences.
