Add status Column to the Image Table

[jopemachine]

Motivation  

• We need a dedicated column to indicate the current state of each image (e.g., ready, pulled, deleted).
• This will enable a soft delete mechanism by setting the status to deleted instead of immediately removing the record.

Required Features

• Add a new status column in the Image table (e.g., enum or string type).
• Define default value (ready) and allow future transitions to states like pulled, deleted, etc.

Impact  

• The database schema will be modified to include the new column.
• Existing queries or services that retrieve Image data may need to handle the new status field.

Testing Scenarios  

• Verify that newly created Image records have a default status (e.g., ready).
• Test status updates from ready to pulled and from any status to deleted.
• Validate that existing operations on the Image table still function correctly.
