[bugfix] Fix enable pack functionality to use proper API endpoint (#6157)

## Summary
- Fixed issue where enabling a disabled pack incorrectly triggered
installation instead of using the dedicated enable endpoint
- Added proper `enablePack` method in the manager service layer
- Updated store and component to use the correct API call

## Problem
When users toggled a disabled pack to enable it via `PackEnableToggle`
component, the system was incorrectly calling the install endpoint with
full installation parameters instead of the simpler enable endpoint that
only requires the pack ID.

## Solution
1. **Added dedicated `enablePack` method in `comfyManagerService.ts`**:
   - Uses the `'enable'` task kind with `EnablePackParams`
   - Only requires `cnr_id` parameter (simpler than install)

2. **Updated `comfyManagerStore.ts`**:
   - Created proper `enablePack` function that queues an enable task
- Removed the incorrect aliasing where `enablePack` was pointing to
`installPack`

3. **Simplified `PackEnableToggle.vue`**:
   - Now calls `enablePack` with only required parameters (id, version)
   - Removed unnecessary installation-specific parameters

## Test plan
- [x] Enable a disabled pack and verify it uses the enable endpoint (not
install)
- [x] Confirm the pack is properly enabled after the operation
- [x] Check that the task queue shows "Enabling" message (not
"Installing")
- [x] Verify existing install/uninstall functionality still works

Fixes #6154
