Address QA findings: prefetch reset on re-lock, settings gate, HSL validation

Browse Source 
W-02: Reset hasPrefetched ref when app re-locks so subsequent unlocks
refresh stale cache data.
S-01: Validate localStorage HSL values with regex to prevent CSS injection.
S-05: Defer prefetch until settings are loaded for accurate upcoming_days.
