Gate agent mode behind use_printer_agents toggle

Replace per-printer auto-activation
(is_current_printer_agent_plugin)
with a global experimental AppConfig
toggle, default off: legacy
print-host behavior is unchanged
until the user opts in. The toggle
drives device-tab routing, print
button defaults, connect-button
visibility and sidebar layout, and
dedups machine-select dialog opens.
