refactor: rename Playground.Api to FSH.Api, modernize Aspire setup

Rename:
- Folder: Playground.Api/ → FSH.Api/
- Namespace: FSH.Playground.Api → FSH.Api
- Assembly: FSH.Playground.Api → FSH.Api
- Container: fsh-playground-api → fsh-api
- Migrations: FSH.Playground.Migrations.PostgreSQL → FSH.Migrations.PostgreSQL

Aspire improvements:
- Add WithLifetime(ContainerLifetime.Persistent) for dev containers
- Remove hardcoded OTEL endpoint (Aspire auto-injects)
- Wire Blazor to API via WithReference() + service discovery
- Add WithExternalHttpEndpoints() for dashboard links
- Fix CachingOptions__EnableSsl=false for local Redis
- Add WaitFor(api) on Blazor project

Updated across ~50 files: solution, csproj refs, AppHost, Dockerfile,
CI workflow, docker-compose, VS Code configs, all migration files,
test projects, module refs, Terraform, CLAUDE.md, README, docs, agents.
