Simplify Project Schema

Problem

The Project model is overloaded with budget-related fields that will be moved to a separate table in the future. Currently, creating a project requires filling in too many fields.

Decision

Simplify the Project model to require only: title, description, category (optional). Remove budget and deadline fields entirely from the schema.

Changes

Prisma Schema

Remove from Project model:

• budgetType (ProjectBudgetType enum)
• budgetMin (Decimal)
• budgetMax (Decimal)
• currency (String)
• deadline (DateTime)

Change:

• category from required to optional (nullable)

Remove enum:

• ProjectBudgetType (FIXED, HOURLY)

ProjectCreateDto

Required: title (3-255 chars), description (min 3 chars) Optional: category (ProjectCategoryType)

ProjectUpdateDto

All optional: title, description, category

ProjectResponseDto

Fields: id, title, description, category (nullable), status, customerId, createdAt, updatedAt
