Changes

• using enum where possible
• using using where possible
• using given where possible. I had to keep using implicit val and implicit def in several places because given seems to invoke the scala 3 lazy val implementation, which invokes sun.misc.unsafe, which requires extra security permissions in Elasticsearch. This is covered in Runtime code implementing lazy val should not use sun.misc.Unsafe on Java 9+ (JEP-471) scala/scala3#9013 and it's a variant of same issue I encountered in Dependencies: Upgrade Scala to 3.3.3 #653
• using Conversion where possible.
• removed a couple minor unused/unnecessary things: a trait that we were no longer using, and a Try wrapper in several places that just ends up using .get, a type check that was getting called for every iteration of a while loop.
