#5120 "Status page: what is wrong first".
- A "Needs attention" card heads the Status board: each down monitor with
how long it has been down, and each active alert (firing, acknowledged,
pending, no data) with its condition and how long, linking to its history.
- StatusEntry.since / since_at_least: when the current up/down run began,
from the recent checks (streak_start); "for at least" when every check we
have agrees.
- Counts as stat tiles (Down, Active alerts, Pending, Up); names wrap
instead of being cut off; dots carry their label.
- Uptime and TLS are coloured by status_class against Settings → Thresholds
instead of literal cutoffs; heartbeat pills and DOWN/UP use tokens and
status_badge rather than hex and bold.
- tests/core/test_status_page.py: streak_start cases, and the rows render
with the problem card before the list, each since-time, threshold tones
and no hex colour.

Collapse the three former check types into a single core `Monitor` entity
with one management surface (/monitors), one result table (monitor_results),
and a single scheduled task. Every type can now watch a free-standing custom
destination (optional host_id) — not just a registered Host.
- models: Monitor + MonitorResult replace PingResult/DnsResult; Host loses its
ping/dns facet columns (now Monitor rows linked by host_id).
- checks: monitors/{ping,dns,http}.py pure probes + runner.run_monitor
dispatcher; one monitor_check scheduler with a per-monitor due-filter.
- status: single monitor_status_source replaces the three sources.
- UI: /monitors blueprint (type-aware add/edit/list/widget); host hub shows a
host's linked monitors + "add monitor for this host"; nav + widget registry
+ alert metric catalog rewired. http plugin folded into core and removed.
- migration 0022 merges the http branch, data-migrates host facets +
http_monitors + all three result histories, drops the old tables/columns.
Resolves the per-host ping/dns auto-attach issue (#275): monitors are now
explicit, never auto-added to every host.

Adds a Kuma-style "is everything up?" surface that aggregates heterogeneous
monitor types via a status-source registry (steward/core/status.py): each
type registers an async source(db) -> [StatusEntry]. Core registers ping/DNS;
the http plugin registers its own from setup() so core never imports plugin
tables. Per entry: current up/down, last-30 heartbeat bar, uptime %
(24h/7d/30d), latest latency + response sparkline, and TLS expiry countdown
(HTTP). New /status page (live htmx refresh) + a status_overview dashboard
widget + nav link. Pure-function unit tests for registry + sparkline.
First deliverable of milestone #68 (task #866).
