Expected Behavior

// `routes.ts` 
// compilation should produce compatible imports with verbatimModuleSyntax
import { fetchMiddlewares, ExpressTemplateService } from '@tsoa/runtime';
import type { TsoaRoute } from '@tsoa/runtime';

Current Behavior

// `routes.ts` 
// doesn't separate type imports and is incompatible with verbatimModuleSyntax
import { TsoaRoute, fetchMiddlewares, ExpressTemplateService } from '@tsoa/runtime';

Error: 'TsoaRoute' is a type and must be imported using a type-only import when 'verbatimModuleSyntax' is enabled.ts(1484)

Possible Solution

Could consider respecting the verbatimModuleSyntax compilation flag and adding the runtime import according to it.

Steps to Reproduce

1. Enable verbatimModuleSyntax in tsconfig.json.
2. Compile tsoa using cli or programmatically
3. Compile your project using the tsoa compiled routes
4. routes.ts will cause a compilation error: 'TsoaRoute' is a type and must be imported using a type-only import when 'verbatimModuleSyntax' is enabled.

Context (Environment)

Version of the library: tsoa@6.2.0 Version of NodeJS: v20.11.0

• Confirm you were using yarn not npm: [x]
