Rework the HoS's Energy Shotgun (Varying energy consumption depending on fire-mode + re-adds a toned down self recharge.) (#32104)

* Rebalance HoS's Energy Shotgun

* SLIGHTLY Up the max charge so the gun properly recharges all of its charges, which matters a lot more with the self charge cooldown system.

* Prevent recharge cooldown if 0 power is used.

* Makes the clientside HUD actually update to reflect the changes in firecost and thus max/current charges.

* Properly fix that recharging to just under full issue instead of applying a budget fix to only the eshotgun.

* Clean up the client ammo UI fix.

* Update the self recharger component to comply with maintainer request.

* Remove code that was made redundant by a hotfix from another PR.

* Make the recharge pause on EMP, document things where needed, clean up code as per maintainer request, add a note to make the code better when power is moved to shared.

* Fix another internal issue

* Code cleanup + fix the rapid recharge verb to remove pause.

* cleanup
