feat: for judging entries the entry number needs more robust validation to reduce the potential for error.

Currently when assigning judging entries the use can enter any entry number from 0 to 99. This can produce some erroneous scenarios where the user doesn't even have a carving with the entered number.

Example 1: If a carver has 3 carvings and they got first place in a category a user could enter in something > 3 for the entry number.
Example 2: A user could enter in 0 for a carving entry (this is covered in another story actually).
Example 3: If a carver has 3 carvings and they got first place in more than 1 category a user could enter in entry number 1 for each different category (which would be incorrect as a single carving can only be entered into 1 category).
Example 4: If a carver has more than 1 entry in the same category they could get different ribbons for different entry numbers but they can get multiple ribbons for the same carving.

This is a very complex problem to solve sine we do not inventory each carving when the carver checks in. We have no idea if the carving is in painted or natural. We also have no idea what category a carving is placed in. So validating the right entry number was entered is not a simple solution. This feature should be deferred until a later date.
