Description

• Save and open links with special characters correctly; JavaScript links are blocked.
• Get a suggested shortcut name from the website address, keep custom names, and avoid duplicate names.
• Create webpage shortcuts directly or select files with the mouse or keyboard.
• See consistently aligned file and space previews in shortcut suggestions and global search.

Related Issue

• Fixes Shortcut URLs containing < are stored truncated or HTML-escaped #3793

How Has This Been Tested?

• test environment: macOS, Chromium (Playwright), local Docker backend.
• test case 1: < becomes %3C, & stays unchanged; query and fragment values are preserved when saving/opening.
• test case 2: JavaScript targets are blocked on creation/opening; line separators cannot inject shortcut entries.
• test case 3: File search, duplicate names, keyboard/IME/Escape handling and URL creation during search failure work.
• test case 4: Typing a URL autofills a unique hostname without filename errors; custom names remain editable and survive target changes.
• test case 5: File suggestions appear only for matching files; dropdown spacing matches global search and both use the correct space-image processor.
• Automated checks: 5,544 unit tests passed; typecheck, lint, formatting and build passed.
