rename "incident reports" to "field reports" in UI

[srabraham]

also start using the initialism "IMS #" for incident number and "FR #" for field report number.

This is only a surface-level change, affecting pieces of IMS that are visible to users. There's a bunch more work to do sometime to rename everything else, from persistence to server code to APIs to JavaScript internals.

I was thinking about calling them "field incident reports" but this is less confusing.
