test(eth): gate EIP-1559 chunked-data regression on firmware 7.14.1+

Upstreaming this test as a permanent regression guard rather than a
one-shot bug catcher. Bumping requires_firmware from 7.2.1 (the version
where EIP-1559 support originally landed) to 7.14.1 (the first version
where the access-list ordering bug is fixed) so CI on broken builds
skips this test instead of flagging a known-broken state as a new
regression.

The header comment already documents the affected range
(7.x.0 .. 7.14.0) and the fix landing in 7.14.1.
