feat: Improve "Share" button with engine selection and clipboard support, improve i18n

[HashCookie]

Fix: #187

Reason

• The "Share" button doesn't directly copy the generated link to clipboard
• The selected engine (/Go/Java) is not saved in shared link
• Reference issue: [bug] the "Share" button should directly put the generated link to clipboard, and it should also save the "Language" (Node/Go,Java) #187

Resolve

1. Remove unused useCopy hook and implement new clipboard functionality
2. Add engine selection to share data structure
3. Integrate selected engine type into share URL parameters
