Add unit tests for quote utility functions

[aruneshwisdm]

Summary

The utility functions in apps/web/lib/quotes/utils.ts have no unit tests. These are pure functions with clear inputs/outputs, making them ideal for a first contribution.

Functions to test

• calculateDepositAmount(total, depositType, depositValue) — calculates deposit as percentage or fixed amount
• formatQuoteCurrency(amount, currency) — formats a number as currency with a space after the symbol
• isQuoteExpired(expirationDate) — checks if a quote's expiration date has passed

Files

• Source: apps/web/lib/quotes/utils.ts
• Test file to create: apps/web/__tests__/lib/quotes/utils.test.ts

Acceptance criteria

• Test calculateDepositAmount with percentage type (e.g., 10% of $1000 = $100)
• Test calculateDepositAmount with fixed type (e.g., $200 fixed on $1000 total)
• Test calculateDepositAmount when fixed deposit exceeds total (should cap at total)
• Test formatQuoteCurrency with USD and other currencies (EUR, GBP, INR)
• Test isQuoteExpired with past date (returns true), future date (returns false), and null (returns false)
• All tests pass with pnpm vitest run apps/web/__tests__/lib/quotes/utils.test.ts

Getting started

Look at existing test files in apps/web/__tests__/lib/ for the testing patterns used in this project. The project uses Vitest.
