feat(connections): Connecting state refactor

[jamesarich]

This introduces a new Connecting state to the connection lifecycle, providing users with better visual feedback during the device connection process.

Key changes include:

• Refactoring ConnectionState from an enum to a sealed class to accommodate the new Connecting state.
• Updating the UI to display progress indicators and status text when in the Connecting state:
  • The main navigation icon now shows a "cached" icon and an orange tint.
  • The Connections screen displays a CircularWavyProgressIndicator.
  • DeviceListItem shows a progress indicator instead of a radio button for the device being connected to.
• Centralizing device list rendering logic by creating a reusable DeviceListSection composable, reducing code duplication in BLEDevices, NetworkDevices, and UsbDevices.
• Refactoring the connection handling logic in MeshService to be more explicit and state-driven.

Since the 'enhancements' to Bluetooth connectivity in Version 2.7.7, the Bluetooth connection appears to have become unstable. I have 4 nodes and 2 mobile phones and since the upgrade Bluetooth now constantly disconnects from the nodes and will not re-establish a connection. In the app, it sits there saying 'connecting' but never re-establishes a connection. I've found the only way to get it to reconnect is the Force Stop the app and reboot the node, which isn't great if the node is up the top of a pole.

Never had this issue with Bluetooth before until this update.

Which fw is running on your 'pole node'? - the latest firmware alpha (v2.7.15) seems to be much more solid. Give that a shot.
