chore: add TUI screenshots via VHS with realistic seed data

Screenshots capture 4 views: monitors dashboard (hero), detail panel,
alerts tab, and logs tab. Seed data uses homelab-themed monitors with
a SQL backfill for rich sparkline history, state changes, and log
entries.

Also fixes latencySparkline to color DOWN checks red instead of green
— previously failed checks with 0ms latency rendered as green bars.

-An uptime monitor you manage entirely from the terminal. It runs as a server, exposes an SSH endpoint, and drops you into a full TUI — monitors, alerts, logs, nodes, all there.
+- **6 check types**: HTTP, Push (heartbeat), Ping, Port, DNS, Groups
-
+- **9 alert providers**: Discord, Slack, Email, Ntfy, Webhook, Telegram, PagerDuty, Pushover, Gotify
-Built on [RDGames/go-upkeep](https://github.com/RDGames/go-upkeep). Rewritten for clustering, config-as-code, and a proper dashboard.
+- **Config as code**: define monitors in YAML, apply declaratively, version control your setup
-
+- **HA clustering**: leader/follower with automatic failover
-## Features
+- **Prometheus metrics**: `/metrics` endpoint for Grafana dashboards
-
+- **Public status page**: HTML + JSON, toggle with an env var
-- **6 check types** — HTTP, Push (heartbeat), Ping, Port, DNS, Groups
+- **SQLite or Postgres**: SQLite for single-node, Postgres for production
-- **9 alert providers** — Discord, Slack, Email, Ntfy, Webhook, Telegram, PagerDuty, Pushover, Gotify
+- **Uptime Kuma import**: migrate from Kuma with one command
-- **Config as code** — define monitors in YAML, apply declaratively, version control your setup
-- **HA clustering** — leader/follower with automatic failover
-- **Prometheus metrics** — `/metrics` endpoint, wire it straight to Grafana
