fix: Add 'Delete only from DB' option for duplicate detected scripts

[michelroegl-brunner]

Problem

Users can have duplicate detected script entries (same container_id and server_id) in the database. Currently, for SSH scripts with container_id, the only option is "Destroy" which destroys the actual container. Users need a way to delete just the database record to clean up duplicates without destroying the host/container.

Solution

Add a "Delete only from DB" option in the Actions dropdown menu for detected scripts (SSH scripts with container_id) that:

• Only deletes the database record
• Does NOT destroy the container
• Uses a clear confirmation modal to distinguish it from "Destroy"

Changes

• Added "Delete only from DB" menu item in Actions dropdown for SSH scripts with container_id
• Placed option after "Destroy" with separator to distinguish from destructive action
• Updated handleDeleteScript to use confirmation modal for SSH scripts
• Modal clearly states it only deletes database record, container remains intact
• Allows users to clean up duplicate script entries without destroying containers

Testing

• Verify Delete only removes the database record
• Verify Destroy still works as before (destroys container + deletes record)
• Verify duplicate scripts can be cleaned up without affecting containers
• Verify deleted scripts can be re-detected via auto-detect feature
