fix(ci): sync bun.lock and regenerate SDK output against openapi-ts 0.97.3

Dependabot bumped @hey-api/openapi-ts in package.json but cannot update bun.lock (no native Bun support), so bun install with frozen-lockfile failed in CI. Refreshing bun.lock and the codegen output restores green CI. The 0.97.x regen is backwards compatible on public types (no src/types.gen.ts change); only client.gen.ts, utils.gen.ts, params.gen.ts, serverSentEvents.gen.ts, and the Options generic in sdk.gen.ts move, all with safe defaults.
