remove package-lock.json and adding new pnpm packages

[SORVER]

• package-lock.json removed to use pnpm only
• This pull request updates the project dependencies to add support for validation and transformation utilities commonly used with NestJS. The main changes include adding class-transformer, class-validator, and their related packages, and updating the dependency graph for NestJS packages to include these new libraries.

Dependency additions and updates:

• Added class-transformer and class-validator as direct dependencies, along with their required sub-dependencies (validator, @types/validator, and libphonenumber-js). (pnpm-lock.yaml, package.json) [1] [2] [3] [4] [5] [6] [7] [8] [9]
• Updated all @nestjs/common, @nestjs/core, @nestjs/platform-express, and @nestjs/testing dependency graphs to include class-transformer and class-validator as optional dependencies, ensuring these utilities are available throughout the NestJS ecosystem. (pnpm-lock.yaml) [1] [2] [3] [4] [5] [6]
• Updated snapshots for all affected packages to reflect the new dependencies and their relationships. (pnpm-lock.yaml) [1] [2] [3] [4] [5] [6] [7] [8]

These updates prepare the codebase for using advanced validation and transformation features in NestJS modules and DTOs.
