Add media server cards, and stop re-counting whole libraries every minute

Browse Source 
The counts need the entire library downloaded to compute six numbers — 16.0 MB
from Radarr and 5.5 MB from Sonarr, measured — and they were on the same
one-minute clock as queue depth and health, which pulled ~30 GB a day out of the
arrs to re-count records that had not changed. They now cache for fifteen
minutes against how often the numbers actually move: 7.6s to 3.0s per refresh.

Emby and Jellyfin get a card each: version, CPU, memory, uptime, streams, users
and transcodes, with update/restart flags. Two halves of one question — a server
answering happily at 145% CPU is a different situation from one at 8%, and
neither the app nor the container says so alone.

// ── Live arr data ─────────────────────────────────────────────────────────────

// Six numbers — total, monitored, and the file/episode/album count — and the only way to get them
// from these APIs is to download the entire library and count it. Measured against this install:
// 16.0 MB from Radarr and 5.5 MB from Sonarr, per fetch.
//
// The rest of this payload refreshes every minute because queue depth and health genuinely change
// that fast. These do not: a library gains items a few times a day. Refreshing them on the same
// clock pulled ~21.5 MB out of the arrs every sixty seconds — about 30 GB a day — to re-count
// records that had not changed. The page cache hid it perfectly, which is why it ran that way for
// as long as it did: the cost fell entirely on the background writer and on the arrs themselves.
//
// Fifteen minutes is chosen against how often the numbers move, not how fresh they could be. A
// library count that is ten minutes stale has never been the wrong answer to anything, and the
// discovery scripts that add items run far less often than that.
//
// Keyed per instance URL so two hosts' Sonarrs never share an entry, and only written on success —
// caching an empty result would keep an arr looking empty for fifteen minutes after it came back.
