Task: Contain backend feature mapping

Feature

docs/FEATURES/platform-scaffold.md

Goal

Move backend feature-specific persistence mapping out of the shared AppDbContext body and into the owning Modules/<Feature>/Data folders.

Context

Architecture docs state that current backend feature code stays under Modules/<Feature>. AppDbContext remains the shared EF Core composition point, but feature-owned model configuration should live with the feature entities.

Files Likely To Change

• backend/src/Socialize.Api/Data/AppDbContext.cs
• backend/src/Socialize.Api/Modules/*/Data/*

Constraints

• Do not change API contracts.
• Do not change table names, indexes, or column constraints.
• Do not introduce a broader persistence refactor.

Done When

• Feature entity mappings live under the owning module folders.
• AppDbContext delegates feature configuration to modules.
• Backend build passes.

Validation Commands

dotnet build backend/Socialize.slnx
dotnet test backend/Socialize.slnx
