Watermelon914 63e3e2b256 Fixes an infinite tc glitch (#85543) 
<!-- Write **BELOW** The Headers and **ABOVE** The comments else it may
not be viewable. -->
<!-- You can view Contributing.MD for a detailed description of the pull
request process. -->

## About The Pull Request

<!-- Describe The Pull Request. Please be sure every change is
documented or this can delay review and even discourage maintainers from
merging your PR! -->
See title

Closes #85542

## Why It's Good For The Game

<!-- Argue for the merits of your changes and how they benefit the game,
especially if they are controversial and/or far reaching. If you can't
actually explain WHY what you are doing will improve the game, then it
probably isn't good for the game in the first place. -->
Pretty self-explanatory

## Changelog

<!-- If your PR modifies aspects of the game that can be concretely
observed by players or admins you should add a changelog. If your change
does NOT meet this description, remove this section. Be sure to properly
mark your PRs to prevent unnecessary GBP loss. You can read up on GBP
and its effects on PRs in the tgstation guides for contributors. Please
note that maintainers freely reserve the right to remove and add tags
should they deem it appropriate. You can attempt to finagle the system
all you want, but it's best to shoot for clear communication right off
the bat. -->

🆑
fix: Fixed an infinite TC glitch dupe
/🆑

<!-- Both 🆑's are required for the changelog to work! You can put
your name to the right of the first 🆑 if you want to overwrite your
GitHub username as author ingame. -->
<!-- You can use multiple of the same prefix (they're only used for the
icon ingame) and delete the unneeded ones. Despite some of the tags,
changelogs should generally represent how a player might be affected by
the changes rather than a summary of the PR's contents. -->

* Uplinks

* All /obj/item(s) have a hidden_uplink var. By default it's null. Give the item one with 'new(src') (it must be in its contents). Then add 'uses.'
* Use whatever conditionals you want to check that the user has an uplink, and then call interact() on their uplink.
* You might also want the uplink menu to open if active. Check if the uplink is 'active' and then interact() with it.
