[Android] No way to zoom in Spectate view

[oznogon]

Reproduced with:

• 2022.10.28 official build

Reproduced on:

• Samsung Galaxy S6 running Android 7
• Google Pixel 6a running Android 13

Steps to reproduce:

1. Start a server
2. Select any scenario
3. Select "Spectate (view all)" mode

Expected behavior:

A zoom slider or pinch gestures allow zooming in and out of the view.

Observed behavior:

There's no zoom slider, and no gestures zoom in or out. Single-finger tap-dragging works to pan the view, as expected.

+1 Its the only thing blocking the android build to have full funkcionality, also deleting selected objects, i guess, in GM mode(i know im ghosting an old one, but still)
