Search slows in proportion to the amount of vault entries, such that it can crash ANR and crash the APK.

### Steps To Reproduce

1. Have 2 332 vault entries.

1. Search. The more characters, the slower, until it indefinitely hangs (ANRs).

### Expected Result

Searches for each character should be instantaneous, since it should first search the local database, then query the external one, and update it, or at least render a loading progress indicator if/when not.

### Actual Result

It slows, then, with large strings, hangs:

This causes it to ANR:

If, *in this state*, with `adb shell settings put global enable_freeform_support 1` pre-enabled, I close the application, then re-invoke it and convert it to "Freeform", it crashes:

I've included this because this is solely possible in this state. After re-invoking, I see:

I'd capture a deterministic example, but I don't see `` [^1] in the APK.

### Issue Tracking Info

- [x] I understand that work is tracked outside of Github. A PR will be linked to this issue should one be opened to address it, but Bitwarden doesn't use fields like "assigned", "milestone", or "project" to track progress.
