The analytics page fetched each server's dashboard bundle over SSH one
after another, so the skeleton stayed until every server answered. Start
all fetches at the same time and remember failures, so the page waits
only for the slowest server.
Closes#12347
Every released Sentinel with traffic analytics (1.0.0 and later) has
the dashboard and series routes and the requests, bytes_in and app
fields, so the fallbacks for builds without them are not needed.
- Keep "no data" handling for Sentinel without traffic routes (0.0.x)
- Keep the resource-scope fallback, which Sentinel 1.0.1 needs
Allow validated host file and directory mounts outside resource directories
while protecting external paths from deletion.
Clean up cancelled deployment containers and clear tracked process IDs.
Preserve legacy KeyDB and Dragonfly password parsing, accept server backup
paths without extension restrictions, and allow Compose variable proxy ports.
