android: cap popup width on tablets and large screens (#521)

On tablets in landscape mode, the AirPods connection popup covers the
entire screen because width is set to MATCH_PARENT. This caps the popup
width to 400dp on screens wider than 600dp and centers it horizontally.

Also removes a duplicate gravity assignment in init that was overwriting
the CENTER_HORIZONTAL flag.

Fixes #425

Changing ANC, conversational awareness, ear detection, and other customizations will work without root.
 
-> [!CAUTION]
-> **You must have a rooted device with Xposed to use LibrePods on Android.** This is due to a [bug in the Android Bluetooth stack](https://issuetracker.google.com/issues/371713238). Please upvote the issue by clicking the '+1' icon on the IssueTracker page. DO NOT leave a +1 comment - use the +1 button in the top right of the page next to the "Hotlists" field.  Leaving +1 comment spam makes it impossible for developers to engage in the necessary technical discussion to implement this fix, and will disincentivize the responsible Google developers from engaging.  I don't know a fix for Android versions <13 either. So, this needs a phone running A13+.
-> 
-> There are **no exceptions** to the root requirement until Google/your OEM figures out a fix.
+For everyone else:
+**You must have a rooted device with Xposed to use LibrePods on Android.** 
 
-Until then, you must xposed. I used to provide a non-xposed method too, where the module used overlayfs to replace the bluetooth library with a locally patched one, but that was broken due to how various devices handled overlayfs and a patched library. With xposed, you can also enable the DID hook enabling a few extra features.

-## Changing VendorID in the DID profile to that of Apple

-Turns out, if you change the VendorID in DID Profile to that of Apple, you get access to several special features!
-
-You can do this on Linux by editing the DeviceID in `/etc/bluetooth/main.conf`. Add this line to the config file `DeviceID = bluetooth:004C:0000:0000`. For android you can enable the `act as Apple device` setting in the app's settings.
-
-### Multi-device Connectivity
-
-Upto two devices can be simultaneously connected to AirPods, for audio and control both. Seamless connection switching. The same notification shows up on Apple device when Android takes over the AirPods as if it were an Apple device ("Move to iPhone"). Android also shows a popup when the other device takes over.
-
-### Accessibility Settings and Hearing Aid
-
-Accessibility settings like customizing transparency mode (amplification, balance, tone, conversation boost, and ambient noise reduction), and loud sound reduction can be configured.
-
-All hearing aid customizations can be done from Android (linux soon), including setting the audiogram result. The app doesn't provide a way to take a hearing test because it requires much more precision. It is much better to use an already available audiogram result.
