Adds a CONTRACT_VERSION constant and a version() -> u32 view function so off-chain upgrade tooling can confirm which WASM build a deployed instance is running, matching the pattern already used by sibling contracts (bill_payments::get_version, etc).

Summary
emergency_killswitchhad no way for off-chain tooling to check which build it is talking to, unlike several sibling contracts (bill_payments,remittance_split,savings_goals,family_wallet,insurance,orchestrator) which already exposeget_version().Change
pub const CONTRACT_VERSION: u32 = 1.pub fn version(env: Env) -> u32, a read-only view requiring no auth, returningCONTRACT_VERSION.Purely additive — no existing entrypoint changed.
