chore: add the sign-in form setting entry to 0.11.4

Added records the sign-in form becoming something an administrator can switch
off from the authentication settings. The setting itself is not new, having
been available since before this release as a value read at startup; what is
new is reaching it without restarting the server, so it is recorded as an
addition rather than a change to how signing in works.

The date on the section already stands at the day of this change.

 - 🖥️ **Every command in one terminal.** The terminal pane now carries a tab for each command a model is running alongside your own shell, so you can watch them as they go, move between them and take the shell yourself. [Commit](https://github.com/open-webui/open-webui/commit/54a7a7a7ce22725074c29c7e827446f5dce1421c)
 - 🗣️ **Wording that speaks your language.** A model, tool, skill, function, banner or arena entry can now carry its name, description, starter prompts and valve labels once per language, written in a searchable table in its own editor or brought in as a JSON file, which is refused where a translation drops one of the placeholders the original fills in, and the interface shows the wording for the language it is set to, falling back to the plain text where that language has none.

 - ✏️ **Interface text you can reword.** An administrator can now replace the interface's own wording language by language from a panel in the admin settings, with a replacement refused where it drops one of the placeholders the original fills in. [Commit](https://github.com/open-webui/open-webui/commit/67ac1a4e937271a02bfb02a330aa99dc8192cbf4)
+- 🔓 **Turning off the sign-in form.** The box asking for an email address and a password can now be taken off the sign-in page from the authentication settings, where until now it could only be set before the server started, leaving single sign-on or a directory to sign people in. [Commit](https://github.com/open-webui/open-webui/commit/c4a349651e34bf5d0920bb5e26707ae9961ac39f)
 - 🏷️ **Custom file metadata.** Metadata attached to an uploaded file now travels with the pieces that file is split into and arrives with the retrieved sources, the oversized and internal fields left out.

 - 🗑️ **Quick delete for notes and automations.** Holding Shift over a note in the list or grid, or over a row on the automations page, turns its trailing controls into a delete button, removing the entry in one click rather than the three the menu and its confirmation ask for.

 - ⚡ **Searching without holding up the server.** Searching the text of chats and knowledge now runs beside the rest of the server rather than in front of it, so a long search no longer keeps other requests waiting. [#29621](https://github.com/open-webui/open-webui/pull/29621)
