Linus Rath 5597eadc28 fix: give a server its own sign-in button only when it has a button label #1135
A server entry's OAuth client ID already has a meaning while OAuth is
off globally: it is the registered client that password and TOTP logins
use with Stalwart's require_client_registration. The PR made every such
entry offer OAuth on its own, so existing installs would suddenly run
discovery and show SSO buttons on the login page, and multi-IdP setups
would get one extra button per server.

A server now gets its own button only with both a client ID and a button
label, which no existing config has. The rule lives in `offersOwnOAuth`
with a test. Also:
- the OAuth-only login form uses the selected server's label
- the public config validator checks `buttonLabel` is a string
- the admin hint and `.env.example` say the label enables the button
