perf(mining): one save, at most one restart per thread-count gesture

Every thread-count change on the Mining tab saved settings.json and,
with a miner running, stopped and restarted it: xmrig re-inits its
RandomX dataset and reconnects to the pool, seconds of lost hashing
each time. A drag across the grid did this once per tile crossed (up to
~24), with a "Starting pool miner" toast each; every -/+ click or Enter
did it again.

The tab now hands each pick to the App, which puts the newest in
settings at once and applies it when the input settles: on drag
release, or 0.5 s after the last click, even if the Mining tab was left
in the meantime. The header, RAM estimate and tile fill still follow
the drag live.

- Pool: the restart is decided on the mining-control thread, after every
  earlier start or stop has run. It never starts a miner the user
  stopped, is a no-op when xmrig already runs at that count, and is no
  longer silently skipped when the pick lands in another restart's stop
  window (which left xmrig on the old count).
- Solo: one setgenerate per gesture. A pick made while one is in flight
  now waits for it instead of being dropped (another stale count).
- Clicking the tile that is already selected does nothing; it used to
  save settings and restart the miner.
- With idle thread scaling on, the grid no longer snaps back to the old
  count while a pick is on its way to the miner. A pool auto-balance
  restart keeps a count still queued.
- Idle thread scaling changes the pool count through the same retarget.
  Its correction after a start compares with the count last requested,
  not the xmrig API's lagging report, so it comes about 1 s in instead
  of after the first API report (3-5 s).
- A retarget whose pool config no longer validates shows the same error
  and stops the miner, as the old stop-then-start did.
- While a benchmark runs a pick is saved, but the miner change is
  dropped: the benchmark owns the count until it ends.

A crash within 0.5 s of a pick, or mid-drag, loses that pick; every
clean exit saves it.
