Amnezia Android expects the contents of 'last_config' to be a JSON object
containing a 'config' field which holds the actual protocol configuration string.
Previously we were putting the configuration directly into 'last_config',
which caused the import to fail.
The working QR format from Amnezia app uses:
- 12-byte header: version (0x07C00100) + compressedLen + uncompressedLen
- zlib compressed JSON data
Previously I incorrectly changed this to Qt qCompress format (4-byte header).
This commit reverts to the correct Amnezia-compatible format.
Amnezia Android uses qUncompress which expects:
- 4-byte big-endian uncompressed length prefix
- zlib compressed data (gzcompress output)
Previously we used a custom 12-byte header (version, compressedLen, uncompressedLen)
which was incompatible with Qt's qUncompress.
This fix ensures X-Ray QR codes can be properly decoded by Amnezia VPN app.
