test: give each rotated Android display state its own baseline, run the Android 16 rotation test again

[plum117]

Why

The test "should compare a screen after an orientation change" is skipped on LambdaTest Android 16 (#1274). After setOrientation, the emulator does not always come to the same display state: the rotated page is 952 or 903 pixels wide (display cutout used or left out), and this changes between sessions. The rotated screenshot was named with the viewport at the start of the session (-vp426x848), so one baseline had to match 2 different states (2.674 % mismatch in run 37824184770).

On a local Android 16 emulator the state after the rotation is stable (6 of 6 sessions: 900x295), so this happens only on LambdaTest.

What

• tests/specs/mobile.web.spec.ts: on Android, the tag of the rotated screenshot is the viewport measured after the rotation (-vp${innerWidth}x${innerHeight}), so each rotated state has its own baseline. The Android 16 skip rule for the rotation test is removed.

• New baselines in tests/lambdaTestBaseline/pixel_9_pro/, collected from 6 runs of the LambdaTest Android job (run 37937247476, attempts 1–6, with a temporary autoSaveBaseline: true and an upload, both reverted in this PR):

  Rotation	Android 15	Android 16
  portrait → landscape	vp903x322 (4×), vp952x322 (2×)	vp903x322 (3×), vp952x322 (3×)
  landscape → portrait	vp426x848 (3×), vp426x823 (3×)	vp426x848 (5×), vp426x823 (1×)

  Images with the same name differ only in the status bar (clock, icons) and Chrome's page-load line under the address bar.

• A third Android 16 start state, 426x827 (seen once in run 4): its 6 baselines are added. Without them, a session in that state fails all its checks on main too.

• The 4 old Android 15 rotated baselines (named with the start viewport) are removed.

• The spec comment about the display states names the new state.

Test

• Local Android 16 emulator: pnpm test.local.emus.web setup and compare runs, 7/7 passing; the rotated baseline is named screenshot-landscape-vp900x295-….
• Final run with the normal CI settings (autoSaveBaseline off, the temporary commit reverted), run 37963619201: all 5 jobs pass; the orientation change test passes on Android 15 and 16 in both orientations (Android 14 stays skipped, as before).

Summary

The PR names Android rotation screenshots using the viewport measured after rotation and enables the Android 16 rotation test again.

• Android rotation checks match screenshots to the viewport after the phone turns.

No actionable issues were found. Image contents could not be inspected because this model does not support image input. No tests were run.
