feat: Add agent role assignment and database CRUD tools for AI agent nodes (#12888)

This PR introduces a significant enhancement to the role-based
permission system by extending it to support AI agents, enabling them to
perform database operations based on assigned permissions.

## Key Changes

### 1. Database Schema Migration
- **Table Rename**: `userWorkspaceRole` → `roleTargets` to better
reflect its expanded purpose
- **New Column**: Added `agentId` (UUID, nullable) to support AI agent
role assignments
- **Constraint Updates**: 
- Made `userWorkspaceId` nullable to accommodate agent-only role
assignments
- Added check constraint `CHK_role_targets_either_agent_or_user`
ensuring either `agentId` OR `userWorkspaceId` is set (not both)

### 2. Entity & Service Layer Updates
- **RoleTargetsEntity**: Updated with new `agentId` field and constraint
validation
- **AgentRoleService**: New service for managing agent role assignments
with validation
- **AgentService**: Enhanced to include role information when retrieving
agents
- **RoleResolver**: Added GraphQL mutations for `assignRoleToAgent` and
`removeRoleFromAgent`

### 3. AI Agent CRUD Operations
- **Permission-Based Tool Generation**: AI agents now receive database
tools based on their assigned role permissions
- **Dynamic Tool Creation**: The `AgentToolService` generates CRUD tools
(`create_*`, `find_*`, `update_*`, `soft_delete_*`, `destroy_*`) for
each object based on role permissions
- **Granular Permissions**: Supports both global role permissions
(`canReadAllObjectRecords`) and object-specific permissions
(`canReadObjectRecords`)

### 4. Frontend Integration
- **Role Assignment UI**: Added hooks and components for
assigning/removing roles from agents
