test(DevLogs): Bump test coverage for DevLogs component

[ShivaGupta-14]

DevLogs Test Coverage Improvements

Description

Bumped test coverage for the DevLogs component by adding comprehensive unit tests.

Previously, the component lacked proper test coverage for its core functionality, making future changes riskier to validate.

Tests added:

• Loading, empty, and error states
• Log filtering by level (INFO/WARN/ERROR)
• Copy single log and copy-all functionality

Fixes: #192

Checklist

• Ran npx prettier --write . (for formatting)
• Ran gofmt -w . (for Go backend)
• Ran npm test (for JS/TS testing)
• Added unit tests, if applicable
• Verified all tests pass
• Updated documentation, if needed

Additional Notes

Self-Review

I've reviewed my changes and confirm:

• All tests pass locally
• Mocks are correctly set up for UI components and fetch
• Tests cover the main component behaviors (loading, filtering, copying)
• No duplicate or redundant tests
• Code follows existing test patterns in the project
