R-563: the remote-backup page polls from a status attribute, and „Fut…" is finally translatable

- backups_remote.html: the status stat carries data-status="{{.Offbox.LastStatus}}"; the poll reads
  v.dataset.status === 'running' instead of v.textContent.indexOf('Fut'). The English page could never
  see a running backup before this (slice 1 shipped the English page with that word left Hungarian).
- The running label becomes {{T "backups_remote.fut"}} — hu „Fut…" unchanged, en „Running…".
- 12 backups_remote parity fixtures re-captured. Proven (audit switch/fixture diff): each differs from
  its predecessor ONLY by the data-status attribute and that one poll line; the other 94 are
  byte-identical. The displayed Hungarian is unchanged.
- Tests: TestR563_PollStartsFromAttribute (hu and en), TestR563_AttributeFollowsTheStatus.
  Red-proofed twice: poll back on textContent → both languages fail; word back inline → the English
  page shows Hungarian.
