[MIRROR] Increases midround traitor starting reputation [MDB IGNORE] (#23584)

* Increases midround traitor starting reputation (#78189)

## About The Pull Request

Reputation for traitors serves two goals:
_Primarily_ it is a timelock. Secondarily, it can drive interaction with
secondary objectives by giving you a little reward.

The way that progression traitors work is that reputation is earned
every minute, so that when a developer is adding a new item for the rep
cost they can just write "30 MINUTES" and it means that the item will be
available when 30 minutes have passed, or a little earlier if the
traitor does some secondary objectives.

_Currently_ when traitors arrive on the station they get reputation
equal to _60%_ of the reputation that they would have had if they became
a traitor at the start of the round and then had hidden in a locker
until the current time.
This PR increases that to 100%, so if you are activated as a sleeper
agent 30 minutes into the round you will immediately have 30 minutes of
reputation. With this and your standard 20TC you can buy almost anything
in the uplink, such as a syndicate bomb.

## Why It's Good For The Game

Given that it is primarily supposed to be a time lock to prevent people
from immediately accessing items which can rapidly pivot the round, it
doesn't make sense that late joining traitors are "penalised" in this
way. If we're ok with a roundstart traitor having a bomb right now, we
should be ok with a latejoin one having one too.
As far as I am concerned secondary objectives should be something you do
for a _bonus_, and anything which can drag people away from being 100%
mechanically focused in order to chase the increasing number in favour
of just being able to do their damn gimmick is a good thing.

## Changelog

🆑
balance: Traitors who are activated as sleeper agents or arrive late on
the arrivals shuttle will begin with more reputation and likely be able
to immediately access most of the uplink catalogue.
