feat: implement complete plugin store repository synchronization system

• Fix repository sync implementation in admin API (was TODO placeholder)
- Add full fetch/parse logic for repository.json and plugin index -
Implement robot matching by name/manufacturer patterns - Handle plugin
creation/updates with proper error handling - Add comprehensive
TypeScript typing throughout

• Fix plugin store installation state detection - Add getStudyPlugins
API integration to check installed plugins - Update PluginCard component
with isInstalled prop and correct button states - Fix repository name
display using metadata.repositoryId mapping - Show "Installed"
(disabled) vs "Install" (enabled) based on actual state

• Resolve admin access and authentication issues - Add missing
administrator role to user system roles table - Fix admin route access
for repository management - Enable repository sync functionality in
admin dashboard

• Add repository metadata integration - Update plugin records with
proper repositoryId references - Add metadata field to
robots.plugins.list API response - Enable repository name display for
all plugins from metadata

• Fix TypeScript compliance across plugin system - Replace unsafe 'any'
types with proper interfaces - Add type definitions for repository and
plugin data structures - Use nullish coalescing operators for safer null
handling - Remove unnecessary type assertions

• Integrate live repository at https://repo.hristudio.com - Successfully
loads 3 robot plugins (TurtleBot3 Burger/Waffle, NAO) - Complete ROS2
action definitions with parameter schemas - Trust level categorization
(official, verified, community) - Platform and documentation metadata
preservation

• Update documentation and development workflow - Document plugin
repository system in work_in_progress.md - Update quick-reference.md
with repository sync examples - Add plugin installation and management
guidance - Remove problematic test script with TypeScript errors

BREAKING CHANGE: Plugin store now requires repository sync for robot
plugins. Run repository sync in admin dashboard after deployment to
populate plugin store.

Closes: Plugin store repository integration Resolves: Installation state
detection and repository name display Fixes: Admin authentication and
TypeScript compliance issues
