Let a misfiled series be moved from the finding that reported it

The triage could say Narcos is filed under anime and offer nothing to do about
it. Findings that recorded a destination now carry a Move action, which the AI
tab renders as a button on its own — actions are read from the server, so no UI
knew this existed. Armed like Fix and Dismiss, because it is the only action in
that card that relocates files rather than settings and the undo is another move.
Offered only where the triage said misfiled, never for uncertain: three
narrowings before a file is touched. Re-reads the series from Sonarr first, so a
finding gone stale cannot undo a move made by hand in the meantime.
