Allow character command at low level if they have alts

[Volte6]

Description

The character command only works at level 5 and above. Creating an alt makes them level 1, not allowing them to switch back to their original character.

This fixes it.

Changes

• Command works at level 5 OR if they have alt characters in storage.

Pull Request Overview

This PR enables low-level users with alternate characters to use the "character" command.

• The command now validates that a user either has a character level of 5 or higher or possesses alternate characters.
• The duplicate alt character loading logic has been removed in favor of a single initialization.

• [nitpick] Consider using a consistent variable to check for available alternates (either 'altNames' or 'nameToAlt') across the function to improve clarity.

if user.Character.Level < 5 && len(nameToAlt) < 1 {

internal/usercommands/character.go:73

• [nitpick] Since 'altNames' is already initialized outside and used to check for alternate characters in the prompt, consider refactoring to use this consistently rather than maintaining two separate representations.
