As a mismatch reviewer,
I want to know when the number of IDs I have added exceeded the maximum limit.

Problem:
We need to show to the users an error message when the limit of IDs a user can request in the Mismatch Finder website in one request is exceeded.

Solution:

• An error message is displayed to the users on the first page of the Mismatch Finder below the Text Area component when users exceed the limit of IDs allowed in one go.

Screenshot:

Acceptance criteria:

• An error message is displayed below the Text Area component telling users they exceeded the limit of Item identifiers.
• The error message is shown after the mismatch reviewer clicks "submit".

Notes:
The actual limit of QIDs has not been decided yet. It is still up for discussion in the parent ticket T289945

• During Story writing, we have decided upon 600 QIDs as the maximum limit.
