refactor(01-03): apply recipe.jvm.server + recipe.quality to server module

- Replaces alias(kotlinJvm) + alias(ktor) + application with id("recipe.jvm.server") + id("recipe.quality") — application plugin now applied by the convention
- Removes per-module dep lines (logback, ktor-serverCore, ktor-serverNetty, ktor-serverTestHost, kotlin-testJunit) — all bundled in recipe.jvm.server
- Keeps module-only config: group/version coordinates, application { mainClass.set } + applicationDefaultJvmArgs, implementation(projects.shared)
- File shrinks 23 -> 18 lines; no version literals leak
