test(api validation): add invalid theme query parameter coverage

[dnyaneshwari44]

Description

Fixes #1431

Added a route-level test case in app/api/streak/route.test.ts for the theme query parameter using the invalid value:

theme=nonexistent_theme_name

Changes Made

• Added a new test to verify endpoint behavior when an invalid theme value is provided.
• Confirmed that the API does not crash when an unknown theme is passed.
• Verified that the request returns a valid SVG response.
• Verified that the endpoint falls back to the default dark theme (#58a6ff) for unsupported theme values.

Validation

• Ran the full test suite successfully.
• Verified that all existing tests continue to pass without regression.

Pillar

• 🎨 Pillar 1 — New Theme Design
• 📐 Pillar 2 — Geometric SVG Improvement
• 🕐 Pillar 3 — Timezone Logic Optimization
• 🛠️ Other (Bug fix, refactoring, docs)

Summary

This PR cannot be approved because the required CI checks did not run successfully or are failing.

Required Changes

Issue 1

• Problem: The Vercel build failed.
• Impact: Merging untested changes could break the application build or introduce bugs.
• Required Fix: Please ensure your branch is up to date and resolve the build issues so that all CI checks pass successfully.

[Aamod-Dev]

LGTM! The Vercel deployment failure is a known authorization issue for external contributors and does not indicate a code failure. Approved!

Summary

The PR follows a known pattern of AI-generated superficial test files or redundant assertions that provide little to no meaningful runtime coverage and clutter the repository.

Required Changes

Issue 1

• Problem: The test file creates or simulates interactions on dummy structures, or simply adds redundant 'complementary tests' without real feature value.
• Impact: It provides 0 real test coverage or adds maintenance overhead without fixing actual application bugs.
• Required Fix: Ensure the PR tests actual new runtime behavior and does not just add redundant tests.

Thanks for the review.

While investigating Issue #1431, I noticed that the current implementation does not reject invalid theme values. In validations.ts, the theme parameter falls back to the default "dark" theme, and the route returns 200 OK rather than 400 Bad Request.

Because of this existing behavior, I added a test covering the runtime fallback path using theme=nonexistent_theme_name.

The issue description mentions asserting a 400 Bad Request for invalid theme values. Could you please clarify whether:

1. The expected solution is to add validation logic so invalid themes return 400, or
2. The intended behavior is to keep the current fallback-to-dark-theme implementation and add coverage for it?

I’d be happy to update the PR accordingly once the expected behavior is confirmed.

[Aamod-Dev]

Appreciate you taking the time to submit this PR. I went through the implementation and the approach looks solid.

I'm happy to approve this. Great job!

@JhaSourav07 , @Aamod-Dev

Thank you for the feedback.

I removed the conflicting fallback test and aligned the test suite with the current validation behavior for invalid theme values. All CI checks are now passing successfully.

Please let me know if any further changes are required. Thank you for the review.
