feat: Enhance Device Configuration Screen with Device Info and Telemetry Modes

Browse Source 
- Added a new section to display device information including Device Type, Max Contacts, Max Channels, Telemetry Modes, and Manual Add Contacts.
- Implemented helper methods to convert device types and telemetry modes to user-friendly strings.
- Removed Message History Screen and its references from the Home Screen.
- Simplified message sending logic in Messages Tab to always send to the public channel.
- Introduced a new channel selection feature in the SAR Update Sheet for sending messages.
- Updated MeshCore BLE service to handle send confirmation responses and improved message sending protocols.

### MeshCore Protocol ### MeshCore Protocol
The app implements the MeshCore BLE protocol based on https://github.com/meshcore-dev/meshcore.js The app implements the MeshCore BLE Companion Radio protocol based on https://github.com/meshcore-dev/meshcore.js
**BLE Service**: `6E400001-B5A3-F393-E0A9-E50E24DCCA9E` **BLE Service**: `6E400001-B5A3-F393-E0A9-E50E24DCCA9E`
**RX Characteristic** (write): `6E400002-B5A3-F393-E0A9-E50E24DCCA9E` **RX Characteristic** (write): `6E400002-B5A3-F393-E0A9-E50E24DCCA9E`
**TX Characteristic** (notify): `6E400003-B5A3-F393-E0A9-E50E24DCCA9E` **TX Characteristic** (notify): `6E400003-B5A3-F393-E0A9-E50E24DCCA9E`
#### Command Codes (Client → Device) #### Protocol Overview
- `4`: Get contacts list
- `2`: Send text message
- `39`: Request telemetry
#### Response Codes (Device → Client) The companion radio acts as a 'server', responding to requests from the connected app (the 'client').
- `3`: Contact information
- `7`: Message received
- `0x8B` (139): Telemetry response (Cayenne LPP format)
#### Binary Protocol Format **Frame Delimiters**:
- **BLE**: A frame is a single characteristic value (BLE link layer handles integrity)
- **USB**:
- Outbound (radio → app): Starts with `>` (0x3E), 2-byte length (LE), then frame data
- Inbound (app → radio): Starts with `<` (0x3C), 2-byte length (LE), then frame data
All protocol messages use little-endian byte order. **NOTE**: All uint32 values use Little Endian byte order!
