feat: migrate from HashRouter to BrowserRouter for SEO

Phase 1: WordPress Rewrite Rules
- Add rewrite rule for /store/* to serve SPA page
- Add use_browser_router setting toggle (default: true)
- Flush rewrite rules on settings change

Phase 2: React Router Migration
- Add BrowserRouter with basename from WordPress config
- Pass basePath and useBrowserRouter to frontend
- Conditional router based on setting

Phase 3: Hash Route Migration
- Update EmailManager.php reset password URL
- Update EmailRenderer.php login URL
- Update TemplateOverride.php WC redirects
- All routes now use path format by default

This enables proper SEO indexing as search engines
can now crawl individual product/page URLs.
