feat(website): implement PDPA cookie consent banner and script manager (#14)

### Overview
Implement PDPA & GDPR compliant Cookie Consent Management Platform (CMP) for pps/website:
- **Zustand Store (cookieConsentStore.ts):** Stores consent record (
ecessary, nalytics, marketing) in localStorage with skipHydration: true for Next.js SSR safety.
- **Cookie Banner (CookieBanner.tsx):** Fixed bottom floating banner with Quiet Luxury styling, providing Accept All, Reject Non-Essential, and Customize buttons.
- **Preferences Modal (CookiePreferencesModal.tsx):** Detailed modal dialog allowing users to granularly toggle Analytics and Marketing cookies (Strictly Necessary is locked).
- **Script Manager (ScriptManager.tsx):** Coordinates Google Consent Mode v2 (nalytics_storage, d_storage), conditionally injects GA4, Meta Pixel, and TikTok Pixel, and dispatches homaroma:consent-change DOM events.
- **Footer Revocation Link:** Added Cookie Preferences link in the Support column of Footer.tsx so users can modify/revoke consent anytime.
- **Multilingual Support:** Added localized text for TH, EN, JA, and ZH.
