userCanInstallPython passed null as the token, so anonymous users
accessing via a share link got privilege level NONE from the WithoutUser
path and allowPythonInstall was always false for them.
Read the token from req.session.anonTokenAccess via
TokenAccessHandler.getRequestToken and forward it through
userCanInstallPython to getPrivilegeLevelForProject. For TOKEN_BASED
projects this resolves the anonymous user's access level via
getPrivilegeLevelForProjectWithToken, enabling package installation.
Also update Quarto Slides badge color to #e4637c.
