fix(mcp): banner shows 'disabled' not 'failed' for enabled:false servers (#38204)

get_mcp_status() treated every non-connected server as a failure, so a
server configured with enabled: false rendered as red '— failed' in the
startup banner even though it was intentionally off. Add a 'disabled'
field derived from the enabled flag and render disabled servers dim as
'— disabled' instead.
