refactor(helpdesk-ft): page actionbuttons call no-arg nanoflows (Task 7 method 3)

Replaces the method-2 server-side microflow workaround. Page buttons now call the
offline nanoflows NF_FT_CheckIn / NF_FT_CompleteOffline without arguments (made
parameterless), pairing with the executor nanoflow-param fix + its regression test.
Removes the interim FT.ACT_CheckIn microflow. Nanoflows focus on the CALL
JAVASCRIPT ACTION + connectivity-guard pattern (no object change, since a no-arg
nanoflow gets no object). Final mx check: no StorageLoadException; 3 CE1613 from
the uninstalled NanoflowCommons marketplace module (known-acceptable).
