save() called load(), which DECRYPTS every stored key, then re-encrypted
only the key being saved and wrote the whole dict back. The other
providers' keys were thus persisted in plaintext; on the next load()
Fernet raised InvalidToken on them and they were silently dropped.
Add _load_raw() that returns the still-encrypted on-disk dict (reusing the
existing missing/corrupt-file guards) and have save() build on that, so
untouched providers keep their ciphertext. load() now also goes through
_load_raw(), keeping its behavior identical.

cfg is loaded from prefs and already holds the existing, already-encrypted
password. When the edit form was re-submitted without re-typing the
password, the elif branch called encrypt() on that stored ciphertext,
compounding the encryption on every save and eventually breaking sync with
a decrypt error.
Drop the elif branch: the stored value is preserved as-is, and we only
encrypt when a new password is actually supplied.
