fix(badges): Resolve build errors and restore site styles

This commit addresses several critical issues that were preventing the application from building and rendering correctly.

- **Restores Skeleton UI CSS:** Re-adds the global Skeleton UI CSS imports to `app.css`. This fixes numerous "unknown utility class" errors (e.g., `preset-tonal-secondary`) across the site, allowing components to render with their intended styles again.

- **Fixes Invalid Attribute Name Error:** Corrects the `onsubmit|preventDefault` syntax in the new badge creation and upload forms (`ae_comp__badge_create_form.svelte`, `ae_comp__badge_upload_form.svelte`). The `preventDefault` logic is now handled inside the respective submit handler functions, resolving the Svelte v5 parsing error.

- **Fixes Svelte 5 Binding Error:** Implements a defensive initialization for badge search filter properties directly in the `(badges)/badges/+page.svelte` script. This prevents a `props_invalid_value` runtime error by ensuring that bound store values are not `undefined` when the child search component is rendered.

- **Fixes Invalid CSS Classes:** Replaces incorrect `preset-tonal-*` classes in the legacy `leads_list.svelte` component with standard Tailwind CSS utility classes to prevent further styling-related errors.
