/**
 * Encodes `Midnight.setIsAuthorized` for a bundle spender or ratifier.
 *
 * Prefer requirement helpers or entity `getRequirements()` in app flows; they
 * read `isAuthorized` first and return this transaction only when needed. Use
 * this builder directly when the caller intentionally wants to set or revoke
 * authorization without reading state.
 *
 * @param params.chainId - Chain id used to resolve `Midnight`.
 * @param params.authorized - Supported operator receiving authorization, or any operator losing authorization.
 * @param params.onBehalf - Owner whose authorization mapping is updated.
 * @param params.isAuthorized - Optional target state; defaults to `true`.
 * @param params.metadata - Optional analytics metadata appended to calldata.
 * @returns A deep-frozen `Transaction<MidnightAuthorizationAction>` targeting `Midnight`.
 * @throws {UnsupportedMidnightAuthorizationTargetError} when granting authorization to an unsupported operator.
 * @example
 * ```ts
 * import { midnightSetIsAuthorized } from "@morpho-org/morpho-sdk";
 *
 * const tx = midnightSetIsAuthorized({
 *   chainId: 8453,
 *   authorized: midnightBundles,
 *   onBehalf: user,
 * });
 * ```
