`gen_zkapp_command_from` uses outdated transaction cost profiles

[georgeee]

Mina_generators.Zkapp_command_generators.gen_zkapp_command_from currently generates zkapp transactions with the following profiles: 3:0, 5:1, 5:0. These limits appear to be a holdover from when account updates were more constrained and weren't updated alongside the hard fork.

It's worth bumping the profiles in gen_zkapp_command_from to reflect current limits.

Caveats:

• This generator doesn't produce uniform or max-cost transactions — it targets a specific subclass of zkapp transactions. If bumping the profiles turns out to be non-trivial to reason about or test, closing as won't-fix is a reasonable outcome.

Priority: Nice-to-have for Mesa RC — low. Unlikely to affect testing results in a meaningful way; this is a corner that wasn't updated with the HF rather than a functional gap.
