feat v1.13.0: universality — floors-import wizard, editable icon rules, tap actions (phase 9)

- floors wizard: spaces from the HA floor registry, step-by-step with mandatory
  plan upload per floor, skip support, auto-markup after the last one
- icon rules as data (settings.icon_rules) + in-card editor with live test,
  invalid-regex guard, bilingual defaults, device_class fallback chain
- tap_action (card) + per-device override; security model: card-wide toggle only
  for light/switch/fan/humidifier, explicit override for covers, never lock/alarm;
  600ms long-press always opens the info card
- i18n dictionaries → src/i18n/*.json (+parity tests); light-theme badge fixes
- frontend tests 15→28
