Implement Fetch Token Info

[jaycoolh]

Description:
Provide a simple method to retrieve basic token metadata (e.g., name, symbol, total supply). This feature helps users verify or display token details.

Roadmap Reference: ROADMAP.md > Native Hedera Token Service > Fetch Token Info

Proposed Implementation/Tasks:

• Create a function like getTokenInfo(tokenId).
• Use Hedera Mirrornode API to fetch details.
• Return a structured response (e.g., { name, symbol, decimals, totalSupply }).

Checklist:

• Implement retrieval of token metadata.
• Unit tests verifying returned data.
• Provide minimal documentation or inline usage example.

Additional Context/Notes:

• Optional, but beneficial for debugging or displaying token data in UIs.

Milestone: v0.1 - Token Service
