feat: add one-click copy button for transaction hash and sender address

[ishidad2]

✨ Added Copy-to-Clipboard Button for Transaction Details

A new copy-to-clipboard button has been added to streamline copying key transaction information:

• Transaction hash
• Sender address
• Inner transaction hash (for aggregate transactions)

Each field now includes a small copy icon on the right side with multilingual tooltip support (EN / JA / KO / RU / ZH).

---

🎯 Why This Feature?

Previously, copying transaction-related data required several inconvenient steps:

• Sender address

  Users had to open the explorer link, navigate to the external site, and copy the address manually.

• Transaction hash

  Similar process: click → open explorer → locate hash → copy.

This was unnecessarily time-consuming for a simple task.

➡️ Now you can copy these values instantly in one click, directly from the UI.

---

🛠 Implementation Details

• Added a copy button component using flexbox (right-aligned, minimal footprint)
• Implemented a tooltip with transfer prop enabled to prevent horizontal scrollbar issues
• Added Clipboard API integration with success/error notifications
• Icon size optimized to 0.16rem
• Added translations for all 5 supported languages (EN / JA / KO / RU / ZH)
