Unify Classic and RP Sec accesses

[Emimiyu]

One final issue I take with this PR is the removal of access from the HoS - the offices I can understand to a degree, but everywhere else I do not - I do not consider "no crime here" on any part of the station to be accurate, nor does it align with my experience as HoS. What I find particularly egregious is the removal of ID computer access, which I feel will only serve to make demotions an incredibly lengthy process, requiring the involvement of the HoP or Captain, who may be not present, may be busy, or may be involved in the crime. As it is currently, if a demotion is required, the HoS can use the spare ID console, and it can be done in under a minute; this is how I feel Security business should be conducted - efficiently, in a way that prioritises antag-sec interactions over jumping through bureaucratic hoops that wastes time for both Security and the perpetrator.

In the defense of ID computer access removal, every head of staff has their own ID computer related to their dept and they all can demote anyone from any dept with "Staff Assistant" button. HoS (and so are every other heads) do not need the HoP ID computer to demote someone, except if someone destroy their deparmental ID computer. The ID computer removal doesn't mean that HoS can't demote anyone by any means necessary, it is not true at all to the current game mechanic.

While I do think HoS should keep it because they are second in command next to the HoP who can roll antagonist, especially on situation where Captain goes rogue, the ID access removal do not affect the HoS ability to demote someone to staff assistant.
