Add a station details view

[p-keminer]

Summary

• add a dedicated menu for stations currently held in memory
• show the full raw MAC address, packet count, and selection state without lengthening the compact station list
• adapt the details layout to small and larger displays

Testing

• Focused ESP32-C5 hardware test: the compact row remained readable; details showed the full raw MAC, identity, and packet count without a misleading AP index or overlap, and both back paths worked.

Pull request overview

Adds a dedicated “Station Info” flow to the on-device UI so users can browse stations currently held in memory and view a per-station details screen (full MAC, packet count, selected state) with layout adjustments for small vs larger displays.

Changes:

• Introduces two new menus (wifiStationInfoMenu, stationInfoMenu) and wires them into the WiFi General menu.
• Adds showStationInfo() to render a station details view (MAC/packets/selected) with compact vs roomy layouts.
• Populates a station-selection menu from the in-memory stations list, with an empty-state message when none are present.
