fix(core): make take_from_foundation true by default across all clients

The flag was modelled as an opt-in non-standard rule but moving a card
off a foundation is in fact standard Klondike — disabling it is the
non-standard variant.

Changing the core default to true means every client (desktop, Android,
web) gets correct behaviour without each having to independently patch
the value after construction. Clients that expose a settings toggle
(desktop/Android) can still disable it through SettingsResource.

- game_state.rs: flip default from false → true in new_with_mode
- game_state.rs: rename/update take_from_foundation_disabled_by_default
  test to reflect the new intended default
- solitaire_wasm/lib.rs: remove now-redundant override in new()
  (from_saved keeps its override to fix old saves that serialised false)
