(Bug) Minor - Sign in/ Existing account/ Forgotten password - Backend accepting too short pass, small letters and no numbers and symbols

[Polina1985]

Testing Data: - existing account in the App (forgotten password)

Steps to reproduce:

1. Go to the app Help a paw
2. Enter valid mail
3. Go to "Forgotten password"
4. An email is sent for renewal password
5. Provide short pass - "poli"
6. A confirmation message has been received that is OK.
7. Return to the App with the new pass
8. Enter the new password - "poli"
9. It appears the message "The password is too short"

Actual result:
The pass should not be accepted - cause it is too short, only with small letters and lack of numbers and symbols. The backend should not have accepted the password - "poli"
