Add status timpestamps

[technophile-04]

Description

1. Renamed timestamp => completedAt in seed.sample.json (Because of indentation updated, it looking like I added new stuff :( ) please let me know if I should revert it 🙌 and use 4 space indentation instead at
2. Updated schema to add status timestamps fields
3. Updated firebase functions to respect this changes
4. display createdAt date on frontend cards

---

Also a question currently we are generating timestamp as :

const timestamp = new Date().getTime();

But I saw some people generate timestamp for firebase like this :

import { FieldValue } from "firebase-admin/firestore";
const serverTimeStamp = FieldValue.serverTimestamp();
//  ^ <Full name of the month> dd, yyyy hh:mm:ss <Time zone of your location>

Basically storing its Timestamp object from firebase

And this is how it looks in the firebase document:

Here is chatGPT difference.

Basically, FieldValue.serverTimestamp(); creates a placeholder value and uses timestamp which is generated while writing to firestore. People use this just to avoid using timestamp from client's system clock instead using firebase's cloack.

Since we are not using firebase on client, it doest much affect us but another advantage of FieldValue.serverTimestamp(); its more precise than JS Date since it stores value in nanoseconds where JS Date store in milisecond checkout this

Please let me know if we should use FieldValue.serverTimestamp();, we will needing script to convert current seed timestamps(JS Date) to Firebase Timestamp, it should be though 🙌

This is perfect. Just added a commit to sort completed grants by date DESC
