Fix MetaMask detection in popup context

- Remove FetLife page requirement for Web3 donations
- Remove call to non-existent checkMetaMaskDirect() function
- Simplify Web3 donation event listener to work directly in popup context
- Fix conflicting event listeners that were causing MetaMask detection failure
- Web3 donations now work on any website, not just FetLife pages
