update ktor to user Gradle

[inemtsev]

• Migrated Maven to Gradle build
• Fixed Exposed and PgClient
• Upgraded Ktor to latest
• Some optimizations

Note that the ktor-exposed-dao and ktor-exposed-dsl implementations have been failing consistently since run 809d8655-c602-42a1-9d8c-dc4692738790, i.e. almost 4 months. I actually have a patch to mark them as broken (together with several others such as ktor-pgclient, which has started failing after the upgrade to PostgreSQL 18), but you could take care of it in this PR or fix them, of course.

Ok, I will take a look at them also

Ready to go from my end @volyrique

I can't do a formal review of your PR, nor am I able to review Kotlin code, but unlike before, all tests pass now, so it looks good to me.
