GenSpark AI Developer 13259e881d feat(net): parallel Check + timeout counters + GUI tooltips/order

Networking (anti-freeze):
- Add check_transactions_parallel: pressing "Check" now contacts will-executors
  concurrently with a fast-fail timeout (CHECK_TIMEOUT=8, 1 retry) and a global
  deadline (CHECK_GLOBAL_DEADLINE=30), so a single dead server no longer freezes
  the "checking transaction" dialog for ~140s (old default 10s x 10 retries).
- check_transaction now accepts timeout/max_retries/retry_sleep kwargs.
- Rewrite BalWindow.check_transactions_task to use the parallel helper with live
  progress + an elapsed-time counter "Checking transactions: 2/5 (4s / 30s)".

Reliable elapsed-time counters (Xs / DEADLINEs):
- Replace the unreliable raw heartbeat thread (whose pyqtSignal emissions were
  not marshalled and never repainted) with an on_tick callback driven from the
  CALLING thread in push/ping/check parallel helpers.
- Show the maximum wait too (e.g. "3s / 30s") so the user knows when the
  operation will give up, in the wizard Broadcasting, Ping and Check dialogs.
- Expose networking constants (PUSH_*/CHECK_*/DEFAULT_TIMEOUT) as Willexecutors
  class attributes for a single source of truth in the GUI.

GUI:
- Add hover tooltips: Wizard ("Wizard - Build your will"), Delivery time (truck),
  Check Alive (siren), Calendar, Check (refresh).
- Reorder the Will toolbar to: Wizard | Delivery time | Check Alive | Calendar |
  Check; tighten layout margins so it all fits the Will window.

Tests:
- parallel_ping_test.py: add coverage for check_transactions_parallel (parallel
  timing, global deadline, on_tick from the calling thread) and static checks
  that check_transactions_task/loop_push use the parallel helpers + on_tick
  counter with the 'Xs / Ns' format.

Verified: ruff (0 new issues), 182 official tests pass, parallel/smoke/gui_fixes/
windows_overflow/external_zip tests pass.
