PR Summary

Medium Risk
Updates network fee-related secp syscall gas and OS resource tables plus OS program hashes; changes are mostly cost reductions aligned with measurement but affect billing and proving identity.

Overview
This PR wires secp256k1 and secp256r1 syscalls into the OS resources regression path so their VM step costs are measured from a real __execute__ run instead of being skipped as “unmeasurable.”

The OsResourcesTestContract now exercises each secp syscall (new, add, get point from x, get xy, mul) for both curves. The flow test drops those selectors from UNMEASURABLE_SYSCALLS and treats Secp256k1New / Secp256r1New as syscalls that may appear twice in the trace (second occurrence is ignored when building per-syscall measurements).

Measured costs are written through to blockifier_versioned_constants_0_14_3.json (n_steps for each Secp* entry, mostly slightly lower) and matching SECP*_GAS_COST values in OS constants.cairo. program_hash.json is updated for the rebuilt OS / virtual OS hashes.
