* Dashboard: Add test case for BOM characters in link URLs
This test demonstrates the issue where BOM (Byte Order Mark) characters
in dashboard link URLs cause CUE validation errors during v1 to v2
conversion ('illegal byte order mark').
The test input contains BOMs in various URL locations:
- Dashboard links
- Panel data links
- Field config override links
- Options dataLinks
- Field config default links
* Dashboard: Strip BOM characters from URLs during v1 to v2 conversion
BOM (Byte Order Mark) characters in dashboard link URLs cause CUE
validation errors ('illegal byte order mark') when opening v2 dashboards.
This fix strips BOMs from all URL fields during conversion:
- Dashboard links
- Panel data links
- Field config override links
- Options dataLinks
- Field config default links
The stripBOM helper recursively processes nested structures to ensure
all string values have BOMs removed.
* Dashboard: Strip BOM characters in frontend v2 conversion
Add stripBOMs parameter to sortedDeepCloneWithoutNulls utility to remove
Byte Order Mark (U+FEFF) characters from all strings when serializing
dashboards to v2 format.
This prevents CUE validation errors ('illegal byte order mark') that occur
when BOMs are present in any string field. BOMs can be introduced through
copy/paste from certain editors or text sources.
Applied at the final serialization step so it catches BOMs from:
- Existing v1 dashboards being converted
- New data entered during dashboard editing
