fix: hide selected lazer chains in developer hub docs

[dl-bot-integrations]

Summary

• Keep the developer-hub-only lazer visibility rules simple
• Hide Polynomial and MegaETH via the existing HIDDEN_CHAIN_IDS list
• Leave contract_manager untouched

Verification

• git diff --check
• Attempted pnpm --dir apps/developer-hub test:types; this checkout still has pre-existing workspace/type-resolution issues unrelated to this change

Notes

• Replaced the earlier override-file approach with the existing hardcoded hide list in the Lazer table component only.

🚩 Testnet variants of hidden chains are not hidden

The PR hides "megaeth" and "polynomial" (both mainnet chains), but does not hide their testnet counterparts "megaeth_testnet" and "polynomial_testnet". polynomial_testnet exists in contract_manager/src/store/contracts/EvmLazerContracts.json:44 and would still appear in the testnet docs table. megaeth_testnet does NOT exist in EvmLazerContracts.json, so it wouldn't appear regardless. This may be intentional (testnets are fine to show while mainnets are not yet ready for public docs), but if the intent is to hide these chains entirely, polynomial_testnet should also be added to HIDDEN_CHAIN_IDS.
