Feat: Private/custom rpc flow

[Adamj1232]

Description

This PR adds functionality to to Account Center expanded to allow end users to update their RPC on mainnet.
If the user's primary wallet is on mainnet and disableProtectedRpc is not set to true within the w3o init the button will display to update their RPC.
The RPC endpoint is configurable per chain obj (although this functionality is only enabled on mainnet) and will default to the BN protect RPC

There is also a localstorage set and get that adds a key after/if the user updates their RPC to the defined RPC so the btn will no longer be shown. We could update this to show a green shield in the future if protection is enabled.

interface Chain { /** An optional protected RPC URL - Defaults to Blocknative's private and   * protected RPC to allow users to update the chain RPC within their wallet,   * specifically for private RPCs that protect user transactions  */ protectedRpcUrl?: string ..... } type AccountCenter = { /**  * false by default - This allows removal of the   * Enable Transaction Protection' button within the Account Center   * expanded when set to true  * Can be set as a global for Account Center or per interface (desktop/mobile)  */ hideTransactionProtectionBtn?: boolean ..... }

Looks good! Just a small typo in there I think.
