BUGFIX - Realtor-restricted tabs require a resource restart

[Martinator9001]

(that was a lot of R's)

Overview

This PR fixes the problem with ps-realtor's realtor tabs only working after a resource restart after the given user has loaded in.

Details

Essentially copied what ps-realtor does when the resource starts, and pasted it to also do it when a player loads in.

UI Changes / Functionality

Tabs now work without restarting the resource

Testing Steps

Before:
Start server, Load in, open /housing - no tabs. Restart ps-realtor - tabs appear.
After:
Start server, load in, open /housing - tabs appear.

• Did you test the changes you made?
• Did you test core functionality of the script to ensure your changes do not regress other areas?
• Did you test your changes in multiplayer to ensure it works correctly on all clients?

I think that the problem happened due to the commit merge from bl-realtor, since that's when the problem appeared IIRC

Tried it out with the realtor in my server and there weren't any bugs with the tabs
