fix: remove screen orientation/resize restrictions for Android 16 large screen compatibility

[figonzal1]

Problem

Starting with Android 16, Android will ignore screen orientation and resize restrictions for large screen devices (foldables and tablets). This may cause layout and usability issues for users.

Detected restrictions

<activity
    android:name="cl.figonzal.lastquakechile.core.ui.SettingsActivity"
    android:screenOrientation="PORTRAIT" />

Required actions

• Remove the android:screenOrientation="PORTRAIT" attribute from SettingsActivity in AndroidManifest.xml
• Verify that the SettingsActivity layout works correctly across different screen sizes and orientations
• Test on Android 16 and earlier versions with foldable and tablet devices
