fix(spotless): Exclude generated code from spotless

[redblackcoder]

Summary

Spotless is configured to work on generated code in the repo. This seems unnecesary and makes the spotlessCheck and spotlessApply take long to run.

This PR successfully eliminates unnecessary code generation from the spotlessCheck task, resulting in a 93.5% reduction in execution time (from 1m 33s to 6s).

Performance Metrics

Metric	Before	After	Improvement
Build Time	1m 33s	6s	15.5x faster ⚡
Total Tasks	521 tasks	282 tasks	-239 tasks (46% reduction)
Tasks Executed	516	280	-236 executions

Key Changes Eliminated

Code Generation Tasks No Longer Triggered

The following expensive code generation tasks no longer run during spotlessCheck:

• :metadata-models:generateDataTemplate - Processing 610 schema files
• :metadata-models:generateAvroSchema - Processing 610 schema files
• :metadata-models:generateJsonSchema - JSON schema generation
• :metadata-models:openApiGenerate - OpenAPI code generation
• :metadata-models:compileMainGeneratedDataTemplateJava - Compiling generated code
• :datahub-graphql-core:graphqlCodegen - Generating 1079 GraphQL classes
• :metadata-service:openapi-analytics-servlet:openApiGenerate
• :metadata-service:openapi-entity-servlet:openApiGenerate
• Multiple compilation and resource processing tasks for generated sources

Changes Made

1. Excluded metadata-models from spotless - This project only contains generated code
2. Removed backwards dependencies - Deleted spotlessJava.dependsOn on generation tasks in:
   • metadata-service/restli-servlet-impl/build.gradle
   • test-models/build.gradle
   • entity-registry/build.gradle
   • entity-registry/custom-test-model/build.gradle
3. Updated spotless exclusions - Removed redundant exclusion patterns that are no longer needed

Result

✅ spotlessCheck now runs only on actual source files and does not trigger any code generation pipelines, making the development workflow significantly faster for code quality checks.
