v1.13.0 — floors import, editable icon rules, tap actions

• Floors import wizard: on first run, if the HA registry has floors, the card
  offers to create a space per floor — names prefilled, the (mandatory) plan image is
  requested step by step, any floor can be skipped; after the last one the room-markup
  mode opens automatically. No floors / old HA → the old single-dialog onboarding.
• Editable icon rules: the built-in "name pattern → MDI icon" rules are now data
  (settings.icon_rules) with an in-card editor (⬡ in the header): reorder, delete,
  add, live test field, invalid-regex highlighting, one-click reset to the bilingual
  (EN/RU) defaults. Fallback chain: rules → entity device_class → generic chip.
  Invalid user regexes are skipped safely.
• Tap actions: tap_action card option (info default | more-info | toggle)
  plus a per-device override in the device dialog. Safety model: a card-wide toggle
  only affects lights/switches/fans/humidifiers; covers/valves need a conscious
  per-device toggle; locks and alarm panels never toggle from the plan. A long press
  (600 ms) always opens the info card.
• i18n dictionaries moved to JSON (src/i18n/{en,ru}.json) — new languages can be
  contributed without touching TypeScript; tests enforce key and placeholder parity.
• Light-theme pass: hardcoded dark badge backgrounds replaced with theme variables.
• Tests: 28 frontend (was 15) — tap-action resolver incl. security cases, icon-rule
  compilation/overrides/device-class fallback, floors sorting, i18n parity.
