The save-dialog name field is a focused TMP_InputField, but global discrete
hotkeys kept reading the keyboard every frame, so typing a name like
"Checkers" cycled the pose (C) and shut the server down (K). Add a shared
TypingGuard.IsTyping check (focused TMP/legacy InputField) and short-circuit
the global handlers on it: pose cycle, network dev keys, mode switch, and
paint undo/redo. Movement was already gated out via ControlEnabled.
