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

+### Tap actions: control devices from the plan
+
+By default a tap on an icon opens its info card. In the card settings you can switch
+**Tap on a device** to *Toggle* — a tap then switches lights, sockets, fans and
+humidifiers directly on the plan (wall-tablet style). For safety, a card-wide toggle
+never affects locks, alarms, covers or valves; you can consciously enable toggle for a
+specific device (except locks and alarms — those never toggle from the plan) in its
+edit dialog. A **long press** always opens the info card.
+
+### Icon rules
+
+Which MDI icon a device gets is decided by **icon rules** — editable right in the card
+(the ⬡ button in the header): an ordered list of “name pattern → icon” regexes with a
+live test field, bilingual defaults (EN/RU) and a one-click reset. When no rule
+matches, the entity *device class* decides (thermometer for temperature sensors, etc.).
+
 ### Step 6. Adding your own devices manually
 
 Not everything has to be left to the automation. With the **＋** button in the header you can place any device, group or a **virtual point** on the plan (for example, an "Inlet valve" that does not exist as a device). Set a name, icon, model, link, description and, if you wish, attach a **PDF manual**.
