D0 Part 3: deploy + backups + monitoring in v2

- deploy.html: stacked memory bar -> meter track with two segments
  (committed solid blue, new app 35%-opacity blue), neutral threshold
  ticks; integration status badges -> tags; meta pills -> metarows;
  3-step deploy progress icons -> sprite (check/x/triangle-alert/
  spinning rotate-cw); emoji -> icons or plain text incl. the JS
  confirm string.
- backups.html: storage bars -> meters, disconnected drives render an
  empty track with a neutral 'Leválasztva' (no red), drive-state badges
  -> warn tags, checkmark/warning glyphs -> sprite icons, JS flash/info
  strings de-emojified.
- monitoring.html: bars -> meters in both template and JS-generated
  host-storage markup (usageColorClass now emits nominal/warn/crit);
  Chart.js palette per spec (cpu #2EA8F5, memory #8E7CE8, temp #E0A93E,
  load #5EC4B6 — categorical data series keep distinct hues); tooltip/
  grid/tick colors moved to v2 literals; mem-dist palette rebalanced.
- Templates repo-wide: legacy var(--*) names in inline styles and JS
  string literals renamed to v2 tokens (old names no longer resolve).
- style.css: memory-bar family rewritten for the two-segment meter,
  .ico-spin animation added (reduced-motion respected).
