test(utils): consolidate scattered oneHundredToFraction assertions

[Harshit-Mishra2212]

Description

Following a suggestion by @mahesh-09-12 on #7431 , this PR consolidates the four scattered oneHundredToFraction() describe blocks in utils.test.js into a single, cohesive block for easier maintenance.

Before this change, assertions for the same function were spread across:

• describe("oneHundredToFraction()")
• A duplicate describe("oneHundredToFraction()") inside the format() function logic block (exact duplicate of above)
• describe("oneHundredToFraction() more cases")
• describe("oneHundredToFraction() exhaustive branch coverage")

All unique assertions are preserved in one consolidated describe("oneHundredToFraction()") block. No assertions were removed except the exact duplicate one.

Thanks for following up on the maintainability concern - my earlier suggestion was mainly about the duplicated assertions, but consolidating the scattered blocks also looks cleaner overall.
