Miggo AIRoot Cause Analysis

The vulnerability stems from endpoints that 1) accepted GET requests (lack of @POST annotations) and 2) had insufficient permission checks. The commit adds @POST verb restrictions, switches forms to POST, and implements Item.BUILD permission checks - all classic CSRF fixes. The affected methods handle build triggering and label creation operations, which matches the vulnerability description of attackers being able to 'trigger builds or add labels' via CSRF.
