v1.0.30 — Amber login fixed definitively

- Switched to correct Android intent: URL format per Amber README
- Removed # from callbackUrl (# breaks the intent: format which uses # as delimiter)
- Added pre-redirect in main.tsx: when Amber opens /amber-callback, app redirects to /#/amber-callback so HashRouter can match the route
- All params passed raw (no encoding) inside intent: string as required
