akie c11650bb4c Fix IDOR: Add permission checks to file ancestry endpoints (#14725) ...

Close #14292

## Issue

File ancestry endpoints return folder metadata without validating tenant
permissions, allowing any authenticated user to query arbitrary
`file_id` values across tenant boundaries.

## Affected Endpoints
- `GET /v1/file/parent_folder?file_id={file_id}`
- `GET /v1/file/all_parent_folder?file_id={file_id}`  
- `GET /api/v1/files/{id}/ancestors`

## Root Cause

These endpoints **skip the permission check** that other file operations
(Delete, Download, Move) perform.

## Expected Permission Check

All file operations should follow this 3-step validation:

- Check file.tenant_id
- Check if user_id belongs to this tenant (via user_tenant join table)
- Check KB permission type (team permission)


**Code reference:** This is implemented in `checkFileTeamPermission()`
and used by Delete/Download/Move, but **missing** from
GetParentFolder/GetAllParentFolders.

## Reproduction

```bash
# User B (tenant: BBB) accessing User A's file (tenant: AAA)
curl -H "Authorization: Bearer USER_B_TOKEN" \
  "http://localhost:9384/v1/file/parent_folder?file_id=AAA_FILE_123"

# Result: Returns User A's folder metadata ❌
# Expected: "No authorization." ✅
Fix
Pass userID from handler to service and call checkFileTeamPermission() — same as Download/Delete/Move handlers.
