fix(dto): Fix DTO validation

[Juknum]

The goal here is to remove usage of zod to use NestJS DTO validation

Changed

• Remove zod usage in all controllers to fully use NestJS DTO's
• Remove Entities classes usage in controllers in favor of DTOs; Huge refactoring of types declarations in the submodule, see :
  • fix(dto): Fix API DTO's validation core#2
  • This PR also introduce the usage of MikroORM objects serialization (which should have been done from the begining)
• Renamed src/_mixin to src/base as it makes more sense.
• ImagesService is now a child of FilesService

Added

• Reduced boilerplate of decorators
  • Introduce ApiNotOkResponse that easily merge all 400 responses into 1 decorator (instead of 4)
  • Introduce ApiUploadFile that merge 3 decorators into 1
  • Introduce ApiDownloadFile which is a disguised ApiOkResponse with the data content modified to application/octet-stream to match NestJS Streamable file system.
  • Added ApiForbiddenResponse and ApiUnauthorizedResponse to GuardPermissions decorators as they always comes together
• Added i18nForbiddenException, i18nBadRequestException, i18nNotFoundException and i18nUnauthorizedException which enhance base NestJS https exceptions to add i18n support to it.
• Added a lot of custom class-validators decorators to pre-translate & adapt validations steps for our needs (such as i18nIsEmail() which verify for blacklisted hosts/emails) (this also prevent boilerplate in some cases).

Removed

• TranslateService removed as it was only used for errors/success messages which are now directly translated using i18n... exceptions.
• FilesService.WriteOnDiskAsImage() as ImagesService now inherits from FilesService and super the FilesService.WriteOnDisk() method.

Fixed

• Verify user.verified instead of user.email_verified in AuthService.validateUser()
