feat(es_extended): add Vehicle Identification Number (VIN) system

[gtolontop]

Description

This PR implements a complete Vehicle Identification Number (VIN) system for ESX vehicles, as requested in issue #1638. Each vehicle now has a unique 17-character VIN that persists across plate changes and provides a permanent identifier for vehicles.

---

Motivation

Currently, vehicles are only identified by their license plate, which creates limitations for advanced roleplay mechanics. A VIN system enables:

• Vehicle history tracking independent of plate changes
• Plate swapping/changing mechanics
• Law enforcement investigations
• Insurance and ownership verification systems
• Better vehicle persistence and tracking

---

Implementation Details

• Database: Added vin column (VARCHAR(17) UNIQUE) to owned_vehicles table with index
• Automatic Generation: Vehicles without VIN automatically receive a unique 17-character alphanumeric VIN
• Vehicle Class Enhancement:
  • Added vin field to CVehicleData
  • Added getVin() method to retrieve VIN
  • VIN stored in entity state for network sync
• Utility Functions:
  • ESX.GenerateVIN() - Generates unique VIN with database collision check
  • ESX.GetExtendedVehicleFromVIN(vin) - Find vehicle by VIN
• Admin Command: /getvehiclevin [plate] for testing and debugging
• Backward Compatibility: Existing vehicles receive VIN on first spawn

Usage Example

-- Get vehicle VIN
local xVehicle = ESX.GetExtendedVehicleFromPlate("ABC123")
if xVehicle then
    local vin = xVehicle:getVin()
    print("Vehicle VIN: " .. vin) -- Output: 1ES1234567890ABCD
end

-- Find vehicle by VIN
local xVehicle = ESX.GetExtendedVehicleFromVIN("1ES1234567890ABCD")
if xVehicle then
    local plate = xVehicle:getPlate()
    print("Vehicle with this VIN has plate: " .. plate)
end

Admin command usage:
/getvehiclevin ABC123
Shows notification: Vehicle VIN: g1ES1234567890ABCDs
