fix(dashboard): SessionHistoryPage source badge uses raw text-cyan-300

[OneStepAt4time]

Bug

SessionHistoryPage uses text-cyan-300 for the 'audit+live' source badge instead of the CSS var equivalent.

File: dashboard/src/pages/SessionHistoryPage.tsx line 57

if (source === 'audit+live') return 'text-cyan-300 bg-[var(--color-accent-cyan)]/10 border-[var(--color-accent-cyan)]/25';

Should be text-[var(--color-accent-cyan)].

Impact: Source badge text color doesn't adapt to light theme.
