fix(android): resolve plugin registration with capacitor.plugins.json

- Add capacitor.plugins.json with correct DailyNotification plugin entry
- Use 'classpath' field instead of 'classname' for Capacitor 6 compatibility
- Add annotation processor dependency to plugin build.gradle
- Plugin now successfully registers with Capacitor bridge

Fixes: PluginLoadException and plugin availability issues
Resolves: DailyNotification plugin not loading despite manual registration
