Changes for warnings (mods can warn users, show up in modlog)

Not just the modlog entries, but the UI for issuing warnings also. Shouldn't be too difficult, as it could mostly be copied from the way reports are done.

This can wait for 1.1.0 IMO.

Hi, can I work on this issue?

[dessalines]

Sure! Lmk if you need any assistance.

Try as much as possible to copy-paste from existing components (or add functionality to them). These are very similar to reports, so the components could look similar.

Hi @dessalines, I’ve implemented the warning UI flow, but testing on cloud backend instances gives inconsistent backend errors (new row for relation \"modlog\" violates check constraint \"modlog_check\").

Should I validate this issue only against a local backend, or is cloud testing (like voyager) acceptable?

[dessalines]

I've dropped that constraint for now. LMK if you run into any other issues.

We'll need to reset that entire test instance anyway in a week or so, since we have a lot of DB changes.
