refactor governance:show for viem

[aaronmgdr]

we are converting our commands to use viem + celo/actions instead of contractkit and web3.

Follow the pattern of other commands that have been converted such as commands/network/info.ts, commands/network/whitelist.ts and commands/transfer/celo.ts

Convert commands/governance/show to use viem.

Here’s a step-by-step plan to refactor commands/governance/show to use viem and celo/actions, based on your requirements and the patterns from other migrated commands:

Step 1: Review the Current Implementation

Open commands/governance/show.
Understand its logic, all web3/contractkit interactions, and what data it fetches/displays.
Step 2: Identify Equivalent viem + celo/actions APIs

For each contractkit/web3 interaction, find the equivalent in viem and celo/actions.
Review other refactored commands (e.g., commands/network/info.ts, commands/network/whitelist.ts, commands/transfer/celo.ts) for migration patterns.
Step 3: Refactor to Use viem and celo/actions

Replace contractkit/web3 logic with viem and celo/actions where possible.
Mirror logic and output exactly; do not change behavior or formatting.
If a particular interaction is tricky or not directly supported, you may keep that section using web3/contractkit (but document this in code comments).
Step 4: Ensure Code Style Consistency

Match code style, structure, and error handling to the other recently refactored commands.
Step 5: Manual Testing

Run the refactored command against a testnet/mainnet (as appropriate).
Confirm the output matches the original command for all scenarios.
Step 6: Automated Test Verification

Run existing tests for commands/governance/show.
Ensure all tests pass and that the test files themselves are unchanged.
Step 7: Documentation and Comments

Add clear comments for any part left on web3/contractkit, explaining why.
If any external or tricky logic remains, note it for future full migration.
Step 8: Prepare and Submit PR

Add a concise PR description noting:
The migration to viem/celo/actions,
Any parts not migrated (if applicable),
Confirmation that tests pass and behavior is unchanged.
