fix: docker container actions update row immediately (optimistic UI), keep list visible during reload

- Row badge updates to 'stopping…'/'starting…' instantly on click
- Buttons disabled while action runs so no double-clicks
- List stays visible while refreshing after action (no blank flash)
- container-remove changed to POST so body passes through proxies correctly
