Graywolf RXT test build 84fe4d11

RXT test build based on Graywolf 0.14.14. Commit: 84fe4d1.

• Improve TM-D700 and TM-D710 initialization and recovery after radio power cycles, USB removal, manual Reconnect and Graywolf restart. Recognize TM-D710P, handle delayed startup replies and restore KISS when the radio returns to command/monitor mode.
• Add serial connection details and a working Reconnect button. Allow changing a serial port to a persistent by-id path without colliding with another saved profile's internal name.
• Fix numeric overlays in compressed APRS positions: transmit 0-9 as a-j and decode them back to digits. This fixes reports such as F6DEV-7 being rejected as Invalid uncompressed location.

After upgrading, restart Graywolf and refresh the browser (Ctrl+F5). Keep the profile matching your radio. Use a persistent by-id serial path on Linux. TM-D700 and TM-D710P profiles select band A: verify its frequency before connecting. Serial baud must match the radio's computer port; radio packet speed is a separate setting. Existing configuration and keys are retained.

Validation: physical TM-D700 and TM-D710P tests covered initialization, reception, radio transmission, power-cycle recovery, USB replug, manual Reconnect and Graywolf restart. Go tests, 585 Web tests and the Web build passed from a clean checkout. Cross-platform packages and SHA-256 checksums verified before publication.

Limits: other D710 variants were not physically tested. The corrected compressed report was generated and sent locally; fresh APRS-IS confirmation remains pending. A completely silent radio reset cannot be detected until the radio produces observable serial data.
