test(lifecycle): add dedicated electrumx.bats suite

Same shape as bitcoin-knots.bats and lnd.bats so the 20× release-gate
exercises electrumx through the same state matrix it uses for the other
two core apps. electrumx previously had a single TCP-port check inside
required-stack.bats; this adds destructive + cascade-destructive tiers.

10 @test cases:
* read-only: presence, valid state, TCP port (50001) reachable, no
  orphan containers beyond {electrumx, archy-electrs-ui}
* destructive: stop, start, restart, TCP port recovers within 120s of
  cold restart (longer than bitcoind because electrumx replays its
  index against bitcoind on start)
* cascade: uninstall, reinstall (240s timeout for index rebuild)

With this suite, the three single-container core apps (bitcoin-knots,
lnd, electrumx) now have parity coverage. Multi-container stacks
(btcpay, mempool, fedimint) come next.
