A number of fixes

[EvvC]

Hi! I installed this package and had to make some changes before it worked.

1. /src/Google2FA:7 should implement TwoFA, not TwoFa - case trouble.
2. /js/LitTwoFA.vue:82 should be instead of
   - I saw base64 instead of QR.
3. /dist/2fa.js should be rebuilt accordingly.
4. In documentation https://litstack.io/docs/3.x/packages/2fa#user-model $table->string('two_fa_secret') creates 255 length field. I got 'two_fa_secret' generated value length 256.

Oops, sorry for point 2. There should be img, not div.
