Add authentication with login, registration, and password recovery

[nathanncrt]

As a user, I want to be able to log in, create an account, and reset my password, so that I can securely access and manage my account.

Context / Problem

Currently, the application does not provide a proper authentication system:

• There is no dedicated login page
• Users cannot create an account
• There is no "forgot password" functionality

This leads to:

• Inability for users to securely access the application
• Frustration when credentials are lost
• Lack of basic account management features

Proposed Solution

Implement a complete authentication system including:

• A login page with email and password
• A registration (sign-up) page for new users
• A "forgot password" feature allowing users to reset their password

@Hypertopic/ethnographie Thank you for your suggestion.

Tickets must conform to INVEST principles.

If a ticket can be split into several simpler and independent feature, fix or improvement then it must be.
This is very important:

• to let the choice to the stakeholders of picking and prioritizing the parts they really want,
• to deliver your contributions with a reduced "time to market".

If your "complete authentication system" includes three parts, this probably means that you should have three tickets.
