fix(a11y): fix ProgressRing text label contrast and add no-restricted-syntax lint rule for text-accent

ProgressRing used text-accent (#a1dcd8) on a percentage text label —
same WCAG 2.1 AA failure as #341. Switched to text-primary.

Also adds ESLint no-restricted-syntax rule (scoped to *.svelte files) that
blocks future text-accent usage in JavaScript string literals inside Svelte
class expressions. The rule caught both violations at once; both are now fixed.
The rule is scoped to .svelte files so test assertions against 'text-accent'
strings in .spec.ts files are unaffected.
