didavila 463626da0c feat: add .spec.ts generation for models, mappers, repositories and use-cases
Add 4 new Mustache templates for generating unit test specs:
- model-entity.spec.mustache: tests instantiation, property setting, mock builder
- mapper.spec.mustache: tests per-property DTO→Entity mapping, instanceof, all fields
- api.repository.impl.spec.mustache: tests HTTP method, response mapping, error propagation
- api.use-cases.impl.spec.mustache: tests repository delegation, observable forwarding

Generator changes:
- Add uppercaseHttpMethod to TagOperation for spec HTTP assertions
- Add testValue to TagOperationParam for auto-generated test arguments
- Add resolveTestParamValue utility for primitive/complex type test literals
- Add specs counter to GeneratedCount and GenerationReport
- Wire 4 new renderTemplate calls in schema and tag loops
- Update report generator to count .spec.ts files
