fix(store): warn when state is mutated after injector destruction

[arturovt]

patchState and setState previously silently no-oped when called after the
injector was destroyed. This made it hard to diagnose unexpected silent
failures, particularly in SSR scenarios where finalize() operators can
run after the app has been torn down.

Both methods now emit a console.warn that includes the attempted value,
the state path, and a note explaining common conditions under which this
can occur. The warning is gated on ngDevMode in browser builds to avoid
bundle bloat, but always fires when ngServerMode is active — bundle size
is not a concern on the server and silently dropped mutations are critical
enough to always surface in server logs.
