bobbanandClaude Sonnet 5 bf7f73f6b6 Import maintenance windows from Uptime Kuma
New "Import from Uptime Kuma" action on the Maintenance page (operator):
pick an Uptime Kuma integration and a duration, and it starts (or
extends) a maintenance window here for every server whose address
matches a monitor Uptime Kuma currently reports as being in maintenance,
reusing the existing monitor-to-server matching from the Uptime Kuma
integration itself.

Uptime Kuma's metrics endpoint only exposes a monitor's *current* status,
not its scheduled start/end time (there's no API for that), so this
deliberately doesn't try to mirror Uptime Kuma's own schedule -- it starts
a window for the duration you choose, the same bounded/required-end
window this feature has always used. Running it again while Kuma is
still in maintenance extends the same window rather than stacking a
second one; when Kuma later shows nothing in maintenance, already-active
windows are left alone rather than force-ended, since ending them isn't
something only Uptime Kuma's state should decide. Two Kuma monitors that
match the same server are deduped to one window. Monitors with no
matching server are reported back by name so nothing is silently missed,
and monitors that aren't in maintenance are ignored entirely.

The manual "Start maintenance" endpoint's start-or-extend logic (dedupe,
pruning old rows, the response shape) is now a shared
services/maintenance.ts function instead of living only in that route
handler, so the import path can't drift from how a manual window behaves.
Likewise the server-matching helper gained a small toMatchableServers()
so the existing Uptime Kuma monitors route and this new one build the
same match input the same way instead of each parsing server rows on
their own.

No schema change -- imported windows are ordinary maintenance windows;
their Uptime-Kuma origin is only in the reason text ("Imported from
Uptime Kuma (<integration>): <monitor>"), visible in the Active table and
the audit log like any other window.

Verified with 28 backend checks (the refactored manual start/extend
flow as a regression check; roles; unknown/wrong-type/disabled
integration; validation; nothing-in-maintenance; matching including
same-server dedup and unmatched monitors; re-running extends rather than
duplicating; windows left alone once Kuma exits maintenance; upstream
failure; audit entries) and by driving the real Maintenance page against
the real routers in a browser: import, re-import (extends), the
nothing-in-maintenance state, and the viewer view (no edit card, active
windows still visible). Real dev database mtime untouched.

bobbanandClaude Sonnet 5 1a2dd19736 Add an Uptime Kuma integration: monitor status and which server each one watches
New integration, following the existing pattern: config in-app (URL +
API key, credentials encrypted at rest), its own Uptime Kuma page, an
Integrations list entry, a Dashboard widget, and diagnostic-log/
integration-down-alert coverage for free via the shared withDiagLogging
wrapper. Read-only -- no start/stop equivalent exists for a monitor.

Uptime Kuma has no conventional REST API (the dashboard talks to it over
Socket.IO); researched before writing any code, since guessing wrong here
would have cost real time. The one machine-readable, authenticated
endpoint that lists every monitor is its Prometheus exporter at
GET /metrics, gated by HTTP Basic auth -- an API key as the password with
the username left blank on current installs, or the real dashboard
login on installs from before the API-key feature existed. This adapter
authenticates the same way and parses that endpoint's text-exposition
format itself (metrics: monitor_status, monitor_response_time,
monitor_cert_days_remaining, monitor_uptime_ratio; labels: monitor_id,
monitor_name, monitor_type, monitor_url, monitor_hostname, monitor_port),
verified against the documented metric/label set and the actual upstream
source (server/prometheus.js). A malformed line is skipped rather than
failing the whole scrape.

"What server is being monitored for what": each monitor's target (an IP
for TCP checks, or the hostname out of the URL for HTTP/keyword checks)
is matched against your servers' own IPs and hostnames -- reusing the
same kind of match already used in the consistency report -- and linked
to that server's page. Monitors with no single network target (groups,
push monitors, DNS/keyword checks with a complex URL) are left unmatched
rather than guessed at. Uptime Kuma's tags aren't read, since the
Prometheus endpoint doesn't reliably distinguish a tag label from any
other label it might add later.

The username field is the first genuinely optional integration config
field this app has had; IntegrationField gained an `optional` flag
(server validation and both the add/edit web forms honor it) rather than
special-casing Uptime Kuma.

Verified with 48 backend checks (Prometheus text parsing including
escaped quotes, decimals, negative numbers, and malformed lines; TCP vs.
HTTP target/port extraction; every documented status code; server
matching by IP, hostname, and short name, including no-match cases; the
route's real HTTP round trip against a fake Uptime Kuma server, wrong
credentials, upstream failures, roles, wrong/disabled/missing
integration, diagnostic-log entries; the optional-field validation rule)
and by driving the real page and the real Dashboard widget in a browser
against the real routers, including CSV export and column sorting. Real
dev database mtime untouched.

Not verified: a real Uptime Kuma instance. Everything here was checked
against Uptime Kuma's documented metric format, its actual upstream
source, and a fake server built to match both -- not against a live
installation. If your instance's /metrics output differs from what's
documented (older version, unusual monitor types), the parser should
degrade to an empty or partial monitor list rather than error, but that
degradation itself hasn't been observed against the real thing.
