feat: Bumps Android target SDK to 34

[tuliomir]

Acceptance Criteria

• The application build process should target Android SDK 34

Notes about build environment

The application build was run on Ubuntu 22, with the following devices working successfully

• Emulator running Android 13
• Motorola G52 physical device running Android 13
• Emulator running Android 15

To ensure the build was being executed in an environment as reproducible as possible, the following cache clearing script was used:

#!/bin/bash

# Clear global android cache of NDK's
rm -rf /home/my_user/Android/Sdk/ndk/*

# Clear all builds within the project
rm -rf /home/my_user/mobile-wallet/android/.gradle
rm -rf /home/my_user/mobile-wallet/android/build
rm -rf /home/my_user/mobile-wallet/android/app/build

# Clear all leaking gradle processes
cd ~/mobile-wallet/android
./gradlew --stop
pkill -9 -f gradle
cd ~/

Security Checklist

• Make sure you do not include new dependencies in the project unless strictly necessary and do not include dev-dependencies as production ones. More dependencies increase the possibility of one of them being hijacked and affecting us.
