Problem

Players currently lack a formalized system for applying to join factions, which can make faction management disorganized. There is no structured way for faction leaders to review and approve or deny applications, leading to inconsistent processes.

Solution

This PR introduces a faction application system that allows players to apply to join a faction, with faction leaders having the ability to approve or deny applications. Key features include:

• A structured application process where players can view factions and submit applications.
• Faction leaders can review, approve, or deny applications.
• Players can cancel their applications at any time.
• Automatic cancellation of other pending applications if:
  • A player’s application is approved.
  • A player accepts a faction invitation.
  • A player creates a new faction.
• New faction permissions to control who can approve or deny applications.
• Localization support for all added commands.

Testing

• ✅ Verified that players can successfully submit applications and view pending applications.
• ✅ Confirmed that faction leaders can review, approve, and deny applications.
• ✅ Tested that applicants receive a notification upon approval and gain faction membership.
• ✅ Ensured that players can cancel their applications and reapply as needed.
• ✅ Verified that all pending applications are automatically canceled under the correct scenarios.
• ✅ Confirmed no errors on startup and validated functionality in-game.
