[Fix: #108 ] : used ZOD library instead of regex for FormInputs

[PalashChitnavis]

Title: Fix #108

Description:
used ZOD to create schema's.
all schema are in src/constants/zod-schema.tsx
instead of patternValue and patternMessage, zod's schema handles multiple cases

Screenhots (if any):

Before:
Only 1 validation message, which was passed through patternMessage
only message is :

Enter a valid email address.

After:
Created custom messages for all possible cases, so user knows where they're making a mistake.
messages can be:

Email must contain '@'
Email must have a domain after '@' (e.g., 'example.com')
Domain must contain a '.' (e.g., 'gmail.com')

Resolves #108
