fix(setup): fix continue button disabled on refresh in setup 3 (#1211)

This commit resolves an issue where the continue button in setup step 3 remained disabled after a
page refresh even when libraries are toggled. This was happening because
`mediaServerSettingsComplete` state was reset on refresh and not correctly re-initialized.
