bal.core.willexecutors
=======================
Client logic for talking to *will-executor* servers.
A will-executor is an optional third-party service that, for a small fee,
stores the signed inheritance transactions off-line and broadcasts them once
their locktime expires (acting as a dead-man's switch backup).
This module only contains the networking / data-shaping logic (downloading the
server list, pinging servers for their fee and address, pushing transactions,
checking whether a tx is already stored). It is GUI-free: all user
interaction is handled by the Qt layer.

that of the slowest server rather than the *sum* of all of them. A
single dead server can no longer stall the whole batch.
Args:
willexecutors: ``{url: we_dict}`` mapping (mutated in place with the
ping result, exactly like the old sequential ``ping_servers``).
on_each: optional ``callback(url, we_dict, ok: bool)`` invoked from a
worker thread each time a server answers (or fails), so the GUI
can update its list live. Must be thread-safe / marshalled to
the GUI thread by the caller.
max_workers: maximum number of concurrent pings.
timeout: per-request timeout in seconds (fast-fail, no retries).
on_tick: optional ``callback()`` invoked periodically (every
``tick_interval`` seconds) **from the calling thread** while
waiting for servers, so a Qt caller can refresh an elapsed-time
counter from the same thread that drives ``on_each``.
