Improve dialog radiolist robustness in rockchip64_common.inc

[coderabbitai]

Description

Two improvements to enhance the robustness of the dialog radiolist implementation in config/sources/families/include/rockchip64_common.inc:

1. Harden radiolist: set item statuses and a default selection

Some dialog versions require an explicit on/off status. Also preselect the first item to reduce accidental "No SPI image chosen." when the user hits OK without navigating.

Suggested changes:

• Set explicit on/off status for radiolist items
• Add --default-item "1" to preselect the first option
• Applies to lines 317-322 and 333-338

2. Quote dd paths for safety

Quote paths to guard against whitespace and odd characters (low risk here, but cheap to harden).

Suggested changes:

• Quote the input and output paths in dd commands
• Applies to lines 326-327 and 341

Summary of Changes

Improvement 1: Radiolist Hardening

• Added --default-item "1" to preselect the first option
• Added explicit on/off status for each radiolist item
• First item is on, others are off
• Prevents accidental "No SPI image chosen" errors

Improvement 2: Path Quoting

• Quoted all variable paths in dd commands
• Guards against whitespace and special characters in paths
• Low-risk but cheap hardening improvement

These patches address the specific concerns raised in issue #8558 and improve the robustness of the dialog radiolist implementation. The changes are minimal and backward-compatible while providing better user experience and safety.

Patch 2: Set explicit on/off status for radiolist items

The current implementation dynamically builds MENU_ITEMS array with the format ("$i" "$filename" ""). To add explicit on/off status, we need to modify the array building logic:

Summary of Changes

Improvement 1: Radiolist Hardening

• Added --default-item "1" to preselect the first option
• Modified the menu items array building to set explicit "on"/"off" status
• First item gets "on", all others get "off"

Improvement 2: Path Quoting

• Quoted all variable paths in the two dd commands (lines 328 and 349 in the patched version)
• Guards against whitespace and special characters in file paths

These patches directly address the robustness issues identified in issue #8558 and prevent the "No SPI image chosen" error when users accidentally hit OK without navigating the dialog.
