Add class Meta to Models to Change Verbose Names

[snipher-marube]

This pull request introduces changes to the models by adding a class Metato customize the verbose names. This change prevents the pluralization issues where 'keys' was displayed as 'keyss' and 'friends' as 'friendss'.

Changes Made:

• Added class Meta to the Keys and Friends models.
• Set the verbose_name_plural attribute to ensure correct pluralization for these models.

Detailed Changes:

• Keys Model:

  
  from django.db import models

class Keys(models.Model):

model fields

name = models.CharField(max_length=100)

class Meta:
    verbose_name_plural = "keys"

- Friends Model:
```bash
from django.db import models

class Friends(models.Model):
    # model fields
    name = models.CharField(max_length=100)

    class Meta:
        verbose_name_plural = "friends"

Testing

• Verified that the Django admin interface displays the correct plural forms for Keys and Friends.
• Ensured that the rest of the application continues to function as expected with these changes.

Additional Notes

• These changes are purely for improving the readability and accuracy of model names in the admin interface and have no impact on the database schema or application logic.
• No data migration is required for this change.

Thank you for considering this improvement!
