feat(cms): KDS cooking-mode bumps item + modifier visibility

When a card hits `accepted` the items section bumps base font to
1.25rem and modifier/note lines to 1.15rem + medium weight; the
muted grey on modifiers drops to inherited color. All via Vue
`:style` bindings — class-based CSS rules lose to lnbits' upstream
`!important` on Quasar typography utilities (even with our own
`!important`), so inline wins without an arms race.

 orange, `>15min` red) and offers one-tap state transitions.
 
+When a card transitions to `accepted` (driven by `cookingMode(order)`
+in `kds.js`), three inline `:style` bindings kick in:
+
+- the items `q-card-section` switches base font between `1rem` and
+  `1.25rem`,
+- the modifier list (`.text-caption.text-grey-7`) bumps to `1.15rem`
+  + medium weight + `color: inherit` (drops the muted grey),
+- the per-line note (`.text-caption.text-amber-9`) bumps to `1.15rem`
+  + medium weight; color is left alone so it stays amber.
+
+All cooking-mode styling is inline because an upstream `!important`
+rule (likely an lnbits theme override on Quasar's typography
+utilities) defeats class-based CSS rules — even with `!important`
+on our side. Inline `:style` wins without needing the arms race.
+Card chrome and the age-based `bg-{color}-1` from `cardClass()`
+are untouched. The amber
+per-line note keeps its color because only `.text-grey-7` is
+overridden. No background rules; card chrome and the age-based
+`bg-{color}-1` from `cardClass()` are untouched.

 Today the monitor + KDS poll every 5–8 s. SSE / Nostr push is on
 the roadmap.
