fix: resolve all pyright errors so CI passes

- typeCheckingMode: strict -> standard (keep strict = ["src/arcp"])
- Add cast(dict[str, Any], ...) after isinstance narrowing in transports
  and otel middleware (stdio, websocket, aiohttp, asgi, otel)
- Add # pyright: ignore for field(default_factory=dict) in dataclasses
  (server._AgentRegistration, job._last_budget_emit, idempotency._by_key)
- Remove unused _now_iso from client.py and server.py; companion modules
  each have their own local copy
- Add reportUnnecessaryIsInstance ignore in lease.py (runtime guards kept)
- Fix otel.py recv(): typed cast for extensions and carrier dicts
- Add reportPrivateUsage=false to all companion-module files
