blockifier: enable DeployAccount v4 execution

[ron-starkware]

Stack — part 5 of 9 (base: #14814). Targets 0.14.5.

Enables execution of DeployAccount v4 now that the OS can prove it: TransactionVersion::FOUR joins the blockifier's deploy-account version allowlist.

Also fixes a latent bug in Transaction::from_api: when no address is supplied it hard-coded Pedersen for any deploy-account version. It now uses deploy_account.address_derivation_hash(). That path is reachable with None from blockifier_reexecution and apollo_rpc_execution, and is only latent today because those readers cannot parse v4 yet (#15079 fixes the reader, which makes this load-bearing).

Tests: an e2e that deploys a v4 account at the escaped address and invokes from it, plus a from_api unit test pinning the frozen salt-771 vector.
