fix(wallet-modal): add loading state for extension connect, fix Play Store link

- Extension button now shows 'Approve in extension...' spinner while web3Enable waits
- Add generic error fallback for errors not matching 'authorize'/'not found' patterns
- Replace 'Coming soon on Play Store' with real Play Store download link (io.pezkuwichain.wallet)
- WalletConnectModal mobile hint now links directly to Play Store
- Updated in all 6 locales: en, tr, ar, fa, kmr, ckb
