Fixed Block-scoped variable '...' used before its declaration bug with topologicalSortEntities and topologicalSortNamespaces.

Changed enum conversion from z.number().refine(...).meta({ ... }) to z.enum({ ... }).meta({ "meta:enum": { ... } }). meta:enum is for JSON Schema conversion purpose - without it, we lose information about enum names

{
"ServiceProviderTypeDTOSchema": {
    "$schema": "https://json-schema.org/draft/2020-12/schema",
    "enum": [
      0,
      1,
      2,
    ],
    "meta:enum": {
      "BarberShop": 1,
      "Groomer": 2,
      "Hairdresser": 0,
    },
    "type": "number",
  },
}

before:

const ServiceProviderTypeDTOSchema = z
  .number()
  .refine(val => [0, 1, 2].includes(val), { message: "Invalid enum value" })
  .meta({
    values: { Hairdresser: 0, BarberShop: 1, Groomer: 2 },
    enum: [0, 1, 2],
  })

after:

const ServiceProviderTypeDTOSchema = z
  .enum({ Hairdresser: 0, BarberShop: 1, Groomer: 2 })
  .meta({
    "meta:enum": { Hairdresser: 0, BarberShop: 1, Groomer: 2 },
  })

Enum passed as object allows us to use named enums like ServiceProviderTypeDTOSchema.enum.Hairdresser
