refactor: extract apply_applet_toggle, rooms_for_user & natus helpers to utils; DRY toggle views

- epic/utils.py (new): _planet_house, _compute_distinctions, rooms_for_user
- applets/utils.py: apply_applet_toggle replaces 5 copy-pasted toggle loops
- dashboard/views.py: use apply_applet_toggle; fix double free_tokens/tithe_tokens query in wallet(); promote _compute_distinctions import to module level
- gameboard/views.py: use apply_applet_toggle & rooms_for_user; fix double free_tokens query in toggle_game_applets
- billboard/views.py: use apply_applet_toggle & rooms_for_user
- SCSS: %tt-token-fields placeholder in _tooltips.scss; _gameboard & _game-kit @extend it
- epic/tests/unit/test_utils.py (new): coverage for _planet_house fallback path
