fix: copy_url_to_clipboard copies full OSC8 URL instead of single character

OSC8 links were only detected when exact platform-specific modifiers were held (Cmd on macOS, Ctrl on Linux), but copy_url_to_clipboard should work with either. Additionally, OSC8 links were using selectionString() which gets visible text instead of the actual URI. Now we use osc8URI() for OSC8 links and fall back to selectionString() for regex-detected links.

Fixes #7491
