Add a comment box associated with anomalies

[stscijgbot-jwql]

Issue JWQL-212 was created on JIRA by Bryan Hilbert:

From the JWQL user survey (NIRISS team):

Be able to leave freeform comments when submitting an anomaly. This would be enormously helpful! E.g. sometimes I have to click "other" when I really do know what the issue is, but have no way to record that. Or the effect is subtle and I want to record what it is, for future queries or new folks who stumble across that image.

(The submitted mentioned this as one of their top 3 priority suggestions)

For the first option mentioned above, keeping the list of anomalies up to date would solve the issue.

But in terms of allowing comments, perhaps we can include a single "comments" column in the anomaly DB, and then print out that value on the exposure/detector level pages?
