fix(rpcs): remove dead and defunct RPC endpoints for Ethereum (1)

[kenny-ish]

Removes 29 Ethereum Mainnet (chain 1) RPC endpoints from constants/extraRpcs.js that no longer work.

I checked every chain 1 endpoint in the file with an eth_chainId request from two locations (Bangkok and Helsinki), three times two minutes apart on 2026-09-24, and once more right before opening this PR. Only endpoints that failed the same way every time from both locations are removed. DNS failures were confirmed with Google and Cloudflare DNS.

Endpoints that were rate limited, timed out, returned 5xx or failed from only one location are left in, and so are commented-out entries. The wss:// URL on the same NXDOMAIN host as a removed https:// URL is removed as well.

None of these URLs are touched by the open PRs #3169, #3106 or #3173. The diff only deletes whole entries (a URL line or a complete { url, tracking, trackingDetails } object). 30 other Ethereum endpoints answered 0x1 every time and are unchanged.
