feat(frontend/signup+login): improve accessibility and UX

[naorpeled]

• wrapped forms with the form HTML attribute for users to be able to submit using their keyboards
• added type prop to the button shared component (was needed for some form buttons not to act as submit ones)
• adjusted error showing behavior in login page: errors won't be shown when the form is in a loading state or after changing anything in the input fields' values

🛠 Guidelines to remediate hardcoded secrets

1. Understand the implications of revoking this secret by investigating where it is used in your code.
2. Replace and store your secrets safely. Learn here the best practices.
3. Revoke and rotate these secrets.
4. If possible, rewrite git history. Rewriting git history is not a trivial act. You might completely break other contributing developers' workflow and you risk accidentally deleting legitimate data.

To avoid such incidents in the future consider

• following these best practices for managing and storing secrets including API keys and other credentials
• install secret detection on pre-commit to catch secret before it leaves your machine and ease remediation.
