Validation for QID input field

User Story
As someone adding a wikidata item, I don't want to be able to enter an invalid QID for a category.

Acceptance Criteria*

• Confirm the validation pattern below and apply this if correct (this came from ChatGPT)

1. Check for a “Q” Prefix: Ensure that the input begins with an uppercase “Q”.
2. Only Digits After “Q”: The characters after “Q” should consist solely of digits.
3. Minimum Length: The shortest possible QID is “Q1”, so ensure a minimum length of 2 characters.
4. Reasonable Maximum Length: Wikidata’s QID numbers have not yet exceeded 8 digits (as of 2023). Setting an upper limit, such as 12 characters (1 “Q” + up to 11 digits), will allow room for growth without being excessively large.
5. Case Sensitivity: Ensure that the “Q” is uppercase, as lowercase “q” is invalid.
