test(achievements): add timezone normalization boundary tests

[udaycodespace]

Description

Fixes #2480

Added Achievements.timezone-boundaries.test.tsx to verify Timezone Normalization & Calendar Data Boundary Alignment scenarios for the Achievements component.

Added Coverage

• UTC, EST, IST and JST timezone rendering stability
• Calendar boundary date rendering
• Leap year boundary handling
• Locale date formatting validation
• Daylight savings transition scenarios

Thanks for the review.

I've addressed the failing TypeScript issues in Achievements.timezone-boundaries.test.tsx by updating the mock achievement objects to match the current Achievement interface requirements (icon, threshold, currentValue, progress, and valid type values).

Reviewed the test file. A few things to clean up:

1. process.env reassignment (Achievements.timezone-boundaries.test.tsx): Reassigning process.env with a plain object { ...originalEnv } can break Node internals. The rest of the codebase saves/restores just process.env.TZ — follow that pattern instead.

2. Test 5 'DST boundary' doesn't actually cross DST: 2024-03-10T01:59:59Z is ~10h before US Eastern spring-forward. Adding 1h still doesn't cross the transition. Pick a time that genuinely spans it (e.g. 2024-03-10T06:59:59Z + 1s) or drop 'DST' from the test name.

3. Tests don't exercise timezone paths: The Achievements component renders static props and doesn't use any timezone API. These tests verify vitest mechanics, not timezone behavior. If the intent is future-proofing, mention that in the PR description.

Minor: the �i.mock('framer-motion') passes animation props to

, producing React warnings. Inconsistent with Achievements.test.tsx which strips them.

Hi @Aamod-Dev,

Addressed the review comments and updated the tests to focus on actual component behavior.
Also fixed the framer-motion mock and removed the timezone/DST-specific assertions.

Verified locally:

• Achievements.timezone-boundaries.test.tsx → 12/12 passing
• Achievements.test.tsx → 8/8 passing

Pushed the changes. Please take another look when you get a chance.
Thanks :)
