Refactor reload script to server-side only

[shadylua]

This PR refactors the reload script to run server-side only, removing the client-side implementation.

Great work, but I think the spamTimer you added might actually hurt the player experience and in my opinion it’s not a good solution if what you intended is to prevent reload while already reloading using isPedReloadingWeapon would be a better approach

I think this would introduce new problems than improvements:

1 - By moving all the logic server side, we lose the ability to block reload during certain tasks (getPedSimplestTask is client-only).
2 - By moving the bindKey call server side, players lose the ability to change the keybind via the MTA settings menu.

I think the current approach with both client and server logic works best.

We will have to reject this PR for reasons such as what jlillis explained.
Even with event triggers, performance and delays to check states will be subpar and not suitable.
