`gen_zkapp_command_from` uses outdated transaction cost profiles

`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.
