test(utils): add edge case tests for format()

[Thesmoothengineer]

What needs testing

Added additional edge case tests for the format() utility function in utils.js.
Specifically covering:

• Missing nested properties (e.g. {user.age})

• Original string return when no placeholders exist

Current coverage

The format() function already had tests for:

• Simple placeholders
• Multiple placeholders
• Nested property access
• Undefined values

However, missing nested property access and no-placeholder cases were not explicitly covered.

Proposed approach

Added new test cases inside:

js/utils/tests/utils.test.js

The tests ensure:

• Missing nested properties return an empty string
• Strings without placeholders remain unchanged

Checklist

• I have read and followed the project's code of conduct.
• I have checked that no existing tests cover this area.
• I have checked that there is no open PR for the tests I am submitting.
• I have reviewed docs/TESTING.md for testing patterns.
