Three bugs stacked to produce the symptom in issue #409 (move button does
nothing):
1. selectionChanged() was declared in freeterminaleditor.h but had no body
and was never connected to the selection model, so the move button had no
awareness of whether a terminal was selected. The button could appear
enabled with nothing selected, then silently return early in
on_m_move_pb_clicked() at the real_t_vector.isEmpty() guard.
2. The dataChanged→setDisabledMove(true) connection was a one-way trap: any
cell edit (including accidentally opening and closing a type/function
combo, or toggling LED back to its current value) permanently disabled the
move button until reload() was called. There was no tooltip explaining why
the button was greyed out, so the user had no way to recover.
3. FreeTerminalModel::setData() for LED_CELL had no change guard, unlike
LABEL_CELL which checks label != value. Clicking the LED combo while it
was already at the same value still emitted dataChanged and triggered the
disable.
Fix:
- Implement selectionChanged() to enable the move controls only when at
least one row is selected AND there are no pending (yellow) edits.
- Connect it to both selectionModel::selectionChanged and model::dataChanged
so the button state is always consistent with actual UI state.
- Route reload()'s re-enable through selectionChanged() instead of calling
setDisabledMove(false) directly, so the selection state is respected
immediately after a move.
- Add a tooltip to m_move_pb explaining the disabled state.
- Add the missing change guard to LED_CELL in setData().

Before this this commit the terminal strip editor couldn't only work on
the first project opened into this editor, all other project opened
after couldn't be edited.
This is now past, terminal strip editor can now edit every project open
in QElectroTech.
