refactor: remove minimal catalog from renderers, keep in spec, and add simple basic samples

Remove all 'minimal' catalog usage and logic from the renderer packages (Angular and React) to eliminate maintenance burden and catalog ID override hacks. The minimal catalog and its examples remain in the specification for historical reference.

To ensure developers still have simple entry-point examples in the standard Basic Catalog, we have:
- Copied the simple minimal examples into the basic catalog examples directory (prefixed with `00_` so they sort first).
- Renamed the simple login form example to `00_simple-login-form.json` to avoid name collisions with the original basic login form (`09_login-form.json`).
- Added the `capitalize` function definition to the v0.9 and v0.10 basic catalogs, as it is used by the migrated `00_capitalized-text.json` example.
- Re-added the simple tests in Angular as basic `00_` tests, loading from the basic catalog, verifying that renderers can load these simple examples from the basic catalog.

Fixes a2ui-project#1432

-    - Generate a manifest file (`index.json`) for dynamic discovery.

 ## Architecture
 
 - **Agentless**: Unlike other samples, this does not require a running Python agent. It simulates agent responses locally for interactive components (like the Login Form).
-- **Dynamic Loading**: The app automatically discovers and loads _all_ `.json` files present in the v0.8 minimal specification folder at build time. To add a new test case, simply drop a JSON file into that specification folder and restart the dev server.
+- **Dynamic Loading**: The app automatically discovers and loads _all_ `.json` files present in the v0.9 basic specification folder at build time. To add a new test case, simply drop a JSON file into that specification folder and restart the dev server.
 - **Surface Isolation**: Each example is rendered into its own independent `a2ui-surface` with a unique ID derived from the filename.
 - **Mock Agent Console**: All user interactions (button clicks, form submissions) are intercepted and logged to a sidebar, demonstrating how the renderer resolves actions and contexts.
