internal/etl: display meaning of codes on status page

We have enough status codes for ETL fetches that it's hard
to understand the table on the status page. Add a description
for each code.

Migrations

Migrations are managed with the golang-migrate/migrate CLI tool.

To run all the migrations:

migrate -source file:migrations -database "postgres://localhost:5432/discovery-database?sslmode=disable" up

To create a new migration:

migrate create -ext sql -dir migrations -seq <title>

This creates two empty files in /migrations:

{version}_{title}.up.sql
{version}_{title}.down.sql

The two migration files are used to migrate “up” to the specified version from the previous version, and to migrate “down” to the previous version. See golang-migrate/migrate/MIGRATIONS.md for details.
