User — Adopt Domain Exceptions & Unified Error Handling

[Villarley]

Description

Refactor user module to conform to the unified error model.

What is expected

• Use domain exceptions for validation/not found/conflicts.
• Map Prisma not found/unique errors → NotFoundException / ConflictException.

What should be modified

• src/modules/user/presentation/controllers/*
• src/modules/user/* services/use-cases

Tests

• Cover 404 on unknown id, 409 on unique collisions, 400 on invalid DTOs.

Acceptance criteria

• Only domain exceptions used; tests green.
