Release 2.3.0

A share can now hold a private text (a password, a key, a short note)
with its files or on its own. The upload page's new "Private text" card
takes up to 100 KB; the browser encrypts the text and sends it through
the same chunk pipeline as a file, flagged is_text on share_files, so it
gets the share's password, expiry, download limit and cleanup.

The recipient sees the text only after pressing "Show text", which
counts as their download, so a messenger link preview cannot use up a
share limited to one download. The text is left out of the file list,
the ZIP and the file counts; the admin dashboard marks shares that hold
one with "Text".

The website gains a Private text feature card and a fifth phone
screenshot; every screenshot is retaken.
