feat(app): move the autofill decryption prompts to Compose

AutofillDecryptActivity shows the no keys dialog and the entry view's
passphrase dialog in Compose over its transparent FLAG_SECURE window.
The flow starts once, on the first window focus, instead of on every
onStart: Android 14 evicts a screen lock prompt shown before the
activity is on top, and a restart showed a second passphrase dialog.
After a key import it restarts on the next focus. Dismissing the no
keys dialog now finishes instead of leaving an invisible window.
Rotation and resizing no longer recreate the activity; other
recreations cancel the fill.

The passphrase is now cached only after a successful screen lock
prompt, as the entry view does: a passphrase typed after a cancelled
or unavailable prompt was cached whenever the cache feature was on.

PasswordDialog, its layout, dimens.xml and requireKeysExist lose their
last user and go.
