fix(safe): handle Safe-over-WalletConnect schedule/execute/cancel flows

[AntoTG]

• Detect Safe via WC peer metadata (name "Safe{Wallet}" or url
  app.safe.global), reading the live connector instance from
  useConnections() rather than the shallow useAccount() descriptor.
• Skip waitForTransactionReceipt when Safe is connected — the returned
  hash is a Safe-tx-hash, not an Ethereum tx hash, so the receipt poll
  hangs forever. Show the user a "confirm in Safe" toast instead.
• Add 5-minute timeout to waitForTransactionReceipt as a safety net for
  EOAs (and for any Safe-like wallet we may not detect).
• Latch the role/minDelay reads in useTimelockRoles so a flaky RPC
  refetch doesn't make the New operation / Execute / Cancel buttons
  flicker out on mainnet.
• 26 new tests covering Safe detection, the latch, and connectors lib.

• Schedule receipt timeouts now surface a pending/unknown receipt state instead of reporting confirmed scheduling success.
