Make the Kotlin and Android SDKs and their Java examples usable from Java #2096

Tracks PR #2095.

Plan

Goal: Make the generated Kotlin and Android SDKs callable from Java the way their docs show, and make every generated Java example compile.

What changes (all in #2095):

• templates/android/library/src/main/java/io/package/services/Service.kt.twig and templates/kotlin/src/main/kotlin/io/appwrite/services/ServiceTemplate.kt.twig: every Android service method declares @Throws(AppwriteException::class) (matching Kotlin), and all-required upload methods get @JvmOverloads so Java can skip onProgress.
• ID, Permission, Role, Query, Operator, models/InputFile templates (both SDKs) and Android Channel.kt.twig: @JvmStatic plus @JvmOverloads where a parameter has a default, so Java can write ID.unique().
• templates/{kotlin,android}/docs/java/example.md.twig and src/SDK/Language/Kotlin.php: Java examples get try/catch, List/Map imports, a terminated Client, correctly typed numeric list literals, array-enum values and the Android OAuth activity argument.
• Tests: tests/e2e/languages/kotlin/java-examples.php turns every generated docs/examples/java/**.md into a Java class and compiles it; tests/e2e/languages/kotlin/JavaInterop.java runs against the mock server; wired into KotlinJava17Test, Android16Java17Test, Android5Java17Test and tests/e2e/Base.php.

Remaining steps: The linked PR is the full change. Note for release notes: Java users of the Android SDK now need a try/catch (or throws) around calls that previously compiled without one.

Done when:

• fix(kotlin,android): make the SDKs and their Java examples usable from Java #2095 merged with the Kotlin and Android Java17 e2e tests green in CI
• Next Kotlin/Android SDK release ships the change, with the checked-exception note in its changelog
