fix: Fixes stalled connections and infinite throttle (#1796)

> [!Warning]
> **Developer Warning**
> The `PacketThrottle` callback return value is now reversed. `true` indicates the connection is _throttled_.

### Summary
- Fixes an issue where connections get stalled forever
- Fixes an issue where the throttler is not working properly
- Removes account attack limiter
- Rewrites IP limiter
- Removes IP restrictions (they weren't used, and not practical)
- Fixes issue where IP limiter was counting before firewall was blocking.
