- Add services/{http,chain138,explorer,proxmox,dbisCore} + hooks/{useLiveChain,useOnChainBalances}
- Add BackendStatusBar + LiveNetworkPanel components on DashboardPage
- Overlay on-chain META balance on account rows carrying a walletAddress
- Normalize EIP-55 checksum in chain138.getNativeBalance so hand-typed
sample custody addresses (e.g. 0x742d35Cc...bD38) don't silently drop
out of the balance map
- Default RPC: https://rpc.d-bis.org (user-preferred gateway)
- proxmox.ts stays mocked (CF-Access, needs BFF); dbisCore.ts stays
mocked (no public deployment yet)
