feat(es_extended): add SSN

[Kenshiin13]

Description

Adds a new ssn field to the users table and updates player logic to handle Social Security Numbers (SSNs). Introduces a utility function to generate valid, unique SSNs, ensures uniqueness via a database constraint, and integrates SSN handling into player creation and loading.

Motivation

To provide each player with a unique SSN that behaves like a real-world identifier, enabling RP mechanics such as identity verification, criminal records, and administrative checks. This enhances immersion and supports gameplay features that rely on unique player identities.

Implementation Details

• Added ssn column to users table in both SQL schemas, with a unique constraint.
• Updated player creation logic to generate and store a unique SSN when a new player joins.
• Modified player loading functions to fetch and attach SSN to the player object.
• Added a utility function generateSSN() in Lua that ensures valid formatting and uniqueness (with database check using MySQL.scalar.await).
• All SSNs are stored and handled with dashes for readability (e.g., 123-45-6789).

---

Usage Example

-- Server-side
print(xPlayer.getSSN()) -- e.g., "123-45-6789"

-- Client-side
print(ESX.PlayerData.ssn) -- e.g., "123-45-6789"
