feat(hosts): the Hosts list labels its figures and says how long; SLA tab gone; one place to add a host (#5279–#5283)
Hosts list: - CPU and Memory are their own labelled columns (#5279); a silent agent's last readings are greyed, and Status says "agent silent for 7m". - One uptime figure, 30 days, with 24h and 7d on hover. The SLA tab (/hosts/uptime) repeated it and is removed (#5280; one home per fact). - Status is a word with how long ("Down for 12m"); host_status now carries down_since. Edit and Delete live on the host's page only (#5281). - Figures are right-aligned with tabular digits (.table .num), not a monospace face. Agent fleet (#5282): its add-host form is gone, so hosts are added only on Hosts -> Add host. That form was also the only way to get a token for a manual curl install, so that moves to the host's Agent card as "Install manually" (POST /fleet/<host_id>/register), shown on the fleet page as before. "Delete" there reads "Unregister". Add host (#5283): laid out like the add-monitor form; a name clash comes back inline with what was typed instead of a bare text 400; the address is optional, as the host page already allowed.
