fix(workflow): enable source handle connector on End node 

The End (Output) node had `availableNextBlocks` hardcoded to `[]`,
making `isConnectable = false` on its source handle. This hid the
"+" BlockSelector button entirely, preventing users from adding new
connections from the Output node — unlike every other regular node.

Remove `BlockEnum.End` from the empty-list guard in both the memo
and the `getAvailableBlocks` callback in `use-available-blocks.ts`.
The container-level filter (`availableBlocksFilter`) that prevents
End from being added inside Iteration/Loop containers is unchanged.
