Fake mindshield componentry and Implanter (#34079)

* Fake Mindshield (With some bad sprites)

- Add FakeMindshield System and Component

- Add FakeMindsheildImplantSystem and Component

- modify ShowMindShieldIconsSystem to check for FakeMindshields

- add all supporting yaml for the Implants, action and uplink

- add loc file stuff

- add unfinished sprites

* Cleanup, add to thief toolbox, remove metagame

- Move Implant sameness check to AFTER the implant DoAfter
to prevent instant identification of Deception Implants

- cleanup the systems and components

- add the fake mindshield to the Thief toolbox

* part 1 of fixing the folder problem

* Make the fakemindshield sprite folder lowercase

* CR - Move ImplantCheck into shared, cleanup

- Moved ImplantCheck and eventsubscription into Shared

- Remove Client/Server extensions of FakeMindshieldImplantSystem and
FakeMindShieldSystem and make shared Sealed

- make OnToggleMindshield Private, use the event!

* CR - Cleanup extra lines, fix some Prototype

- cleaned up extra liens in ImplanterSystem and
SharedFakeMindshieldSystem from when i was developing

- Uplink catalog no longer lists the implant in 2 spots,
only implants now, also uses the On state action icon

- added a comment about why it's reraising the action event
rather than directly interacting with the FakeMindshield Component

* Fake Mindshield CR:

- Added a comment about IsEnabled

- moved OnFakeMindShieldToggle to Entity<> from Uid, Comp

- fixed some formatting in uplink_catalog

* CR - Add a bit more comment
