## What
`encryption:notify-removal` now prints, on every run, the total number
of **non-deleted** users who still hold legacy browser-encrypted data:
```
4 non-deleted user(s) still have encrypted data.
```
The count is taken before the billing exclusion, so it reflects the full
remaining scope of browser-encrypted data. Soft-deleted users are
excluded (model default scope), as are users whose data is already
plaintext.
## Why
It's the signal for deciding when the browser-side encryption code can
finally be removed: once this reaches zero, nothing in the app depends
on client-side encrypted columns anymore.
## Not changed
Email-sending logic is untouched. Subscribed users are still never
warned — the recipient set continues to go through
`excludeBilledUsers()` exactly as before. This PR only adds a reporting
line.
## Testing
- New test asserts the count spans everyone with encrypted data
(subscribed included), while excluding soft-deleted and plaintext users,
and that sending still skips the subscribed user.
- Full `NotifyEncryptedDataRemovalCommandTest` suite green.
