v0.8.78

Single sign-on keeps the issuer exactly as entered

Fixed

• An OIDC provider's Issuer URL is saved exactly as entered. MikroDash removed its trailing
  slash, so providers whose issuer ends in "/", such as Authentik
  (https://host/application/o/<slug>/) and Auth0, refused every sign-in with "the provider's
  metadata declares a different issuer". If yours was affected, edit the provider, paste the
  issuer again with its trailing slash, and save. Reported in
  #159, thanks
  @zsaat14.

Changed

• Saving a provider checks its issuer. If the provider's published issuer differs from the
  one entered, the save is refused and the form shows the exact value to use. A provider that
  cannot be reached yet is still saved.
• When sign-in is refused for an issuer mismatch, the server log now shows both values.
