Complete SDK generator with full OpenAPI support

[dotunv]

Description

The SDK generator currently has basic functionality but several gaps:

1. Only handles POST operations - GET, PUT, DELETE, PATCH are not supported
2. Uses hardcoded 'TODO' fallback when OpenAPI properties lack examples
3. No query parameter support in generated code
4. No response type inference from schemas

Files:

• apps/api/src/modules/sdkgen/typescript.generator.ts
• apps/api/src/modules/sdkgen/python.generator.ts
• apps/api/src/modules/sdkgen/go.generator.ts
• apps/api/src/modules/sdkgen/curl.generator.ts

Proposed Improvements

1. Support all HTTP methods (GET, POST, PUT, DELETE, PATCH)
2. Generate proper query parameter handling
3. Infer response types from OpenAPI schema definitions
4. Remove 'TODO' fallbacks - use descriptive defaults or skip
5. Add request body type generation from schemas

Acceptance Criteria

• All HTTP methods are supported
• Query parameters are included in generated code
• Response types are inferred from schemas
• No hardcoded 'TODO' fallbacks remain
