Lock Saved Prompts in Deep Diagnosis to Prevent Editing

NetBrain currently does not provide a way to lock a saved prompt within the Deep Diagnosis module, leaving it open to unintended edits once created. This enhancement would add a lock option for saved prompts, preventing modification unless explicitly unlocked by an authorized user. Locking saved prompts would allow administrators to safely delegate their use to junior engineers without risking accidental changes to established diagnostic logic.
