You're not quoting facts, your presenting your opinion.
There is an Azad Kashmir today, you can't simply erase present day realities. The UN will take note of these.
Yes the resolution does talk about what each country needs to do.
The UN will have to bring in its forces due to the sensitive nature of the region, they have done this time and time again. The resolution itself is old and doesn't take into account today's reality.
Oh don't worry the locals will be enough, the AJK regiment will be in civilian clothes.
The UN also has to carry out a referendum, it won't be possible without its forces. You pointing out my examples actually strengthens the argument for UN forces i.e. the potential for conflict is too great, so hence letting Indian administrators do the job simply won't do.
Then please ask for a new UN resolution as per today's date and realities, no point in asking for implementation of UN resolutions of Apr 21, 1948.
While you reach out to UN for new resolutions, ensure they are passed under chapter VII which can only mandate UN forces to come and settle the issue
No resolution under chapter VI can get UN enforcement through its troop.
You have given in your post all the reasons why UN resolutions of 1948 are not implementable today in its current form. That vindicate India's stand.
But you will be disappointed to know that as per Simla agreement, Pakistan is bind to resolve the issue bilaterally and can not reach out to third party anymore. It will be breach of mutual treaty. This is the reason why UN always suggest us to settle it mutually and may mediate in case both parties invite UN to do so. UN too want the nations to honor mutual treaties which are binding as per UN charter.
PS: I am presenting hardcore legal fact, I will be happy to be proven wrong if countered by legal argument, by now you have presented none.
