starknet_os_flow_tests: fuzz test scenario filtering mechanism

[dorimedini-starkware]

Note

Low Risk
Test-only change that adds optional operation filtering and updates fuzz/exhaustive test harnesses to use it; low production risk, but could change fuzz coverage and scenario counts.

Overview
Adds an optional operation filtering mechanism to fuzz scenario generation in fuzz_tests.rs, allowing callers to restrict which FuzzOperationData variants are considered when building random or exhaustive operation lists.

Updates the fuzz test APIs (valid_operations, add_random_operation, get_all_operation_lists, and fuzz_test_body) to accept an optional OperationFilter, and extends test_daily_fuzz_seed to run both the unfiltered suite and a new limited scenario set (call/write/panic/return), while keeping exhaustive and long fuzz tests defaulting to no filter.
