fix: update Polygon CoinGecko ID from matic-network to polygon-ecosystem-token

[0xApotheosis]

Description

Updates the CoinGecko ID mapping for Polygon's native token from matic-network to polygon-ecosystem-token.

After the MATIC to POL migration on September 4, 2024, CoinGecko deprecated the matic-network ID. The old ID now returns empty price data (current_price: {}, circulating_supply: 0.0), causing Polygon to display as $0.00 in the app.

The new polygon-ecosystem-token ID returns live pricing data (~$0.126 USD currently).

Confirmed we can still swap: https://jam.dev/c/036b5160-480f-4962-a9ad-c2b91fa2318e

Issue (if applicable)

closes #10887

Risk

Low Risk - This is a simple string mapping change in the CoinGecko adapter. No transaction logic, wallet interactions, or contract calls are affected.

What protocols, transaction types, wallets or contract interactions might be affected by this PR?

None. This only affects price display data fetched from CoinGecko.

Testing

Engineering

1. Run the app locally
2. Navigate to the Polygon asset page (/assets/eip155:137/slip44:60)
3. Verify the price displays correctly (should show ~$0.12-0.13 USD)
4. Verify market data (market cap, volume, etc.) displays correctly

Alternatively, verify via API:

• Old (broken): curl https://api.coingecko.com/api/v3/coins/matic-network returns empty current_price
• New (working): curl https://api.coingecko.com/api/v3/coins/polygon-ecosystem-token returns live price data

Operations

• 🏁 My feature is behind a flag and doesn't require operations testing (yet)

Test in preview environment:

1. Navigate to any page showing Polygon (POL) price
2. Verify the price is no longer $0.00
3. Verify the price matches current market price (~$0.12-0.13 USD)

Poem

🐰 I hopped through code with floppy ears agleam,
Swapped one token name to mend a broken stream,
From matic-network to polygon-ecosystem-token I flew,
Now numbers unfrozen and dancing anew—yay, woohoo! 🎉

Seems like doing the do, it will need another generation/mergefix, but stamping as it looks sane!
