Show the focus ring on the title form's and display picker's selects too

The fix review found two older rules (#titleForm select:focus, .disp select:focus)
that outranked the new select:focus-visible outline and still removed it.

+Acquired `/tmp/frame-test.lock` before installing or launching anything and

+
+Reinstalled and launched both original APKs in immersive Lepton instances.
+WiVRn again failed at OpenXR 1.1 and 1.0 with the missing timespec extension;
+ALVR again panicked on `ERROR_EXTENSION_NOT_PRESENT`. This repeats the
+unmodified-client test, not the newer installer's automatic compatibility-layer
+path. Neither reached a session that could be paired or exercised further.
+Fresh [journal excerpts and cleanup evidence](evidence/linux-vr/2026-09-29.txt)

+SteamVR's screenshot API returned a 1920×1080 headset capture after each
+launch. Both are uniformly dark: [WiVRn](evidence/linux-vr/2026-09-29-wivrn.png)
+and [ALVR](evidence/linux-vr/2026-09-29-alvr.png). These images do **not** prove
+rendering or a working client. The headset was unworn; visibility, controllers,
+frame rate and motion-to-photon latency could not be judged. The explicit
+OpenXR errors, rather than the dark captures, establish the client blocker.
+
+Both test installs, app data, shader caches, shortcuts, containers and temporary
+capture files were removed. The original Steam and SteamVR process IDs were
+unchanged. No reboot, power action or global setting change was used. Native
+clients remain untested, and no Linux gaming host was available for Valve's
+streaming path. The recommendation below is unchanged.
