Add a search input and filter chips to the web-install board grid,
allowing users to quickly find boards by name, MCU family (ESP32,
ESP32-S3, ESP32-C3, ESP8266), or gateway type (BLE, RF, IR, LoRa,
RTL_433, Pilight). Filters are derived dynamically from the board
data. Shows result count and a clear-all button when filters are
active.
