Commit Message

background balance polling (60 s, lifecycle-aware)

Adds a per-env goroutine that polls the current account + network
balances every 60 s and broadcasts a `balances_changed` event when
anything differs from the previous snapshot. Replaces the "call
assets.list() every 60 s manually from the host" pattern — frontends
can now bind to the stream and refresh reactively.

Go:
- Extracted currentAssets(e, net, acct) helper in wltbase/asset.go
  so the poller + the existing Asset:list endpoint share one code
  path.
- New wltbase/balance_poll.go: balancePoller struct, pause/resume/
  Nudge methods, and a run loop keyed on a 60-s ticker + kick chan.
  Started from env.init() alongside the cache-cleanup loop.
- Lifecycle:update now pauses the poller on `background` / `paused`
  and resumes on `foreground` / `resumed` / `active`. Resume kicks
  an immediate poll so the UI reflects anything that happened while
  backgrounded (incoming tx, price tick, etc.).
- Diff key: "<acctId>/<netId>" + per-asset Key → Amount.String().
  Network or account switch forces a broadcast on the next poll so
  the UI isn't stuck on stale balances.

Dart:
- New BalancesChangedEvent (sealed subclass of LibwalletEvent) with
  typed getters: network, account, assets.
- client.balanceChanges stream filters events to BalancesChangedEvent.
- Barrel export updated.
