ci: stop installing the removed Android SDK "tools" package

[BrawlerXull]

android-actions/setup-android@v3 installs "tools platform-tools" by default. Google removed the legacy "tools" package from its SDK repository between 2026-09-14 and 2026-09-15, so sdkmanager now exits with "Failed to find package 'tools'" and every workflow that uses the setup-rust-android composite action fails before Flutter runs (Flutter CI, Nightly Build & Log, Nightly F-Droid).

The runner image and cmdline-tools version were identical in the last passing and first failing nightly runs; only the remote repository changed. Install platform-tools only; cmdline-tools already replaces the old SDK Tools.
