Add mocha tests for web/common-function.js unpacker_filter and helpers

[OluchiEzeifedikwa]

Covers any(), mergeObjects(), and unpacker_filter() with a regression case for #1546 (multiple leading comments losing formatting).

Description

Adds mocha tests for web/common-function.js, covering any(), mergeObjects(), and unpacker_filter(). Includes a regression test for the multiple-leading-comments bug fixed in #1546, so this class of bug can't silently reappear.

Fixes Issue: #1547

Test plan

• ./node_modules/.bin/mocha js/test/web/test_common-function.js passes (10/10)
• Full existing mocha suite still passes
• jshint clean on the new file

Before Merge Checklist

• Source branch in your fork has meaningful name (not main)
• JavaScript implementation
• Python implementation (NA)
• Added Tests to data file(s) (NA — new mocha spec file, not a data-driven test fixture)
• Added command-line option(s) (NA)
• README.md documents new feature/option(s) (NA — no user-facing feature added)
