gretel 3bbd43cc1b Fix KISS beacon frame formatting and add sync pattern
Two issues were resolved with KISS interface beacon transmissions:

1. Fixed frame length handling to meet minimum length requirements (15 bytes) for
   TNCs like Direwolf. Previously, raw beacon data was being sent directly,
   causing frame length errors:

```
<<< Data frame from KISS client application, channel 0, total length = 11
  000:  c0 00 44 4e 39 54 54 2d 31 35 c0                 ..FOOBAR-15.
Frame length 8 not in allowable range of 15 to 2123.
ERROR - Invalid KISS data frame from client app.
```

2. Added standard 0xAA 0xAA sync pattern to improve radio modem synchronization
   and compatibility with packet radio protocols like FX.25 and IL2P.

This ensures:
- Proper frame length for TNC compatibility
- Better bit synchronization with standard sync pattern
- Improved reception reliability
- Compatible with both KISS TNCs and packet radio protocols

```
