feat: add new flamey logo and favicon

- Created `assets/logo.svg` with a new gradient flame design.
- Created `assets/favicon.svg` based on the logo.
- Updated `build.mjs` to copy `assets/` to `dist/` and adjust paths in `landing/index.html`.
- Updated `landing/index.html` to use the new logo and favicon.
- Updated `dashboard/index.html` to include the new logo and favicon.
