Add salt to password hashing and improve security

[Anshv784]

Fixes #49

Problem:

• Passwords were hashed without an explicit salt, making them weaker.

Solution:

• Added bcrypt salt (10 rounds) to the signUp function.
• Updated user.save() to use await for proper error handling.
• Password verification remains secure with compareSync.
