[BUG]: CardContentProvider uses the wrong authority uri in parallel builds

### Checked for duplicates?

- [x] This issue is not a duplicate

### Does it also happen in the desktop version?

- [x] This bug does not occur in the latest version of Anki Desktop

### What are the steps to reproduce this bug?

1. Follow the instructions in https://github.com/ankidroid/Anki-Android/wiki/AnkiDroid-API, namely `Gradle dependency` and `Manifest changes required on Android SDK 30+`, while replacing `com.ichi2.anki` with `com.ichi2.anki.a` (or another parallel build)
2. Execute a query with the content resolver, e.g.

```kt
val res: Cursor? = contentResolver.query(
FlashCardsContract.Note.CONTENT_URI_V2,
FlashCardsContract.Note.DEFAULT_PROJECTION,
null,
null,
"${FlashCardsContract.Note._ID} desc"
);
```

### Expected behaviour

A non-null `Cursor` is expected. Instead, the following error message is logged: `Failed to find provider info for com.ichi2.anki.flashcards`

This is because AnkiDroid.A's manifest has set `CardContentProvider`'s authority uri to `${applicationId}.flashcards`, which in the parallel build expands to `com.ichi2.anki.a.flashcards`.
https://github.com/ankidroid/Anki-Android/blob/17748efe929a60ac4b1308b9a27358ae20f8a6e6/AnkiDroid/src/main/AndroidManifest.xml#L659-L666

If I try using that instead of `FlashCardsContract.Note.CONTENT_URI_V2`, i.e.
```kt
val res: Cursor? = contentResolver.query(
Uri.parse("content://com.ichi2.anki.a.flashcards/notes_v2"),
FlashCardsContract.Note.DEFAULT_PROJECTION,
null,
null,
"${FlashCardsContract.Note._ID} desc"
);
```

the following exception is thrown:

```
FATAL EXCEPTION: main
Process: com.blah.app, PID: 15508
java.lang.IllegalArgumentException: uri content://com.ichi2.anki.a.flashcards/notes_v2 is not supported

at android.content.ContentResolver.query(ContentResolver.java:1114)
at com.blah.app.MainActivity.stuff(MainActivity.kt:33)
...
```

The parallel build's content provider now responds, but since it still matches on the incorrect `FlashCardsContract.AUTHORITY`, the uri is deemed invalid
https://github.com/ankidroid/Anki-Android/blob/e9fe00726a48f7d347081379de8cb2334fbd80a6/AnkiDroid/src/main/java/com/ichi2/anki/provider/CardContentProvider.kt#L397

### Debug info

AnkiDroid Version = 2.19beta6 (638d0e29cd91c49d6ca672ebc2494997751160ac)

Backend Version = 0.1.42-anki24.06.3 (24.06.3 d678e39350a2d243242a69f4e22f5192b04398f2)

Android Version = 12 (SDK 31)

### (Optional) Anything else you want to share?

One way might be to have `CardContentProvider` construct its own copy of `FlashCardsContract.AUTHORITY` using ~~`R.string.applicationId`~~ `BuildConfig.APPLICATION_ID`, before passing it to the matcher
