Fix custom range controls dropping extended command arguments

[Cipulot]

Summary

Preserve all custom-menu command arguments when updating range controls.

The range update path previously extracted only the channel and command ID, dropping additional command arguments such as a layer or item index.

For a control defined as:

["id_custom_slider_id", 0, 2, 4]

changing its value to 7 incorrectly sent:

channel=0, command=2, value=7

instead of:

channel=0, command=2, layer=4, value=7

Firmware expecting the extended argument could therefore update the wrong setting or interpret the value as an index.

Fix

Range SET commands now:

1. Remove only the UI identifier.
2. Preserve every remaining command argument.
3. Append the encoded one-byte or multi-byte value.

Tests

Added regression coverage confirming that:

• Additional command parameters are preserved for one-byte range values.
• Additional command parameters are preserved for multi-byte range values.

Verification

• npm test
• npx tsc --noEmit
• Prettier check
