Novy cooker hood

Proposed change Adds a `fan` entity to the Novy Cooker Hood integration, controlling the hood motor over the same 433.92 MHz OOK link as the existing light entity. The protocol is one-way (no feedback), and pressing the remote's `+` / `-` only steps the speed by one. To support `set_percentage` reliably the entity uses a calibration model: each speed change first sends 4 `minus` presses to guarantee the hood is at level 0, then sends N `plus` presses to climb to the target level (1-4 mapped to 25/50/75/100%). This always lands at the requested speed regardless of prior state, at the cost of a …

Proposed change Add a 500ms gap between consecutive RF presses so the Novy hood firmware sees them as distinct button events. The hood debounces RF frames received within a short window into a single press. Without a delay, multi-step sequences (`set_percentage`, `increase_speed` with N steps, the calibration in `_async_set_level`) collapse into one press, which is why issue #171398 reports the fan getting stuck at 25% whenever a higher percentage is requested. 500ms was the lowest value that proved reliable across testing with an ESPHome RF proxy and a CC1101 module. Broadlink wasn't …
