Feature/inactive subscriptions

[sokratis1988]

This feature enables users to mark a subscription as inactive, catering to those who wish to monitor both active and inactive subscriptions. Inactive subscriptions will be visually distinguished at the bottom of the display through subtle CSS styling. Moreover, these inactive subscriptions will be omitted from the overall statistics. Additionally, when at least one subscription is set to inactive, a new statistical indicator will appear, providing a count of the inactive subscriptions.

• By default, subscriptions are active, which is why the form displays the checkbox as selected to avoid confusion.
• I have withdrawn the modifications made to createdatabase.php and have adjusted the default value in the database to true, as specified in the migration file 000006.php.

Please check the comment I made on the migration.
If I am not being clear, or you don't have the time, I already have a branch with this feature mostly implemented. I can just clean it up and merge it.
