Refactoring code in public/src/client/topic/postTools.js

[luciafang]

I made the following changes:

• Exposed the PostTools function checkDuration to test cases.
• Reduced the cognitive complexity of PostTools checkDuration from 18 to 15.
• Created a new test file named test/checkDuration.js to test the function.
• Passed all test cases, and did not introduce new errors.
• Passed all lint checks.

Resolves #422
