Show Start/Stop/Restart Podman progress in a log modal

Same pattern already used for container update checking (P.openLogModal)
— these can take a while (storage checks, container stop grace periods,
...) and are exactly the actions someone reaches for when something's
actually wrong, so a button that just sits there disabled with no
feedback until it's done isn't good enough. "Refresh Status" stays inline
(quick, read-only, no modal needed).
