FlowSphera 1.12.1 release notes

Delete the mail server (Settings → General → Mail server): asked for in a window of its own that says what stops — scheduled reports are not sent, e-mail notifications are switched off (their recipients are kept); Telegram, webhooks and the SIEM go on.
The «Sign in with» choice of the sign-in page looks like the fields above it (it was a plain grey list).
README (EN / UK) and docs for 1.10–1.12: reports, interface load, sign-in through the directory, API tokens, webhooks and the SIEM, with new pictures from the demo.
