Pipe v0.49.1

The description matches what Pipe does

• The tagline is now "A sysadmin that never sleeps, does the routine work itself and asks about what matters" (in
  Polish: "Admin, który nie śpi, rutynę robi sam, a o ważne sprawy pyta"), in both READMEs, on the website, in the
  search and link-preview descriptions and on the social preview images. The old "never touches anything without
  asking" stopped being true in v0.48.0
• The example conversation on the website shows Pipe fixing the nginx config by itself, with a backup and a check,
  and asking before deleting old reports. The "on its own / after your yes / never" table lists what Pipe really
  does without asking
• The README demo GIFs were recorded again: the nginx fix runs without an approval card, marked "without asking"
• The pipe web welcome and the Telegram /start message say that routine fixes happen by themselves and important
  things wait for your yes; the empty Changes tab mentions changes made without asking too

Polish documentation

• The Polish docs (docs/pl/) are written with Polish characters (ą, ę, ł, ó, ś, ż...) instead of plain ASCII,
  like the Polish README and website

Fixes

• The language switch on the website and in the docs is vertically aligned with the other links in the top bar
• scripts/demo/record.py works again (it now opens the map tab first), and scripts/demo/social_preview.py
  renders the social preview images
• A CLI reconnect test no longer hangs now and then (the fake backend could stop before accepting the connection)
