[Task](Heureka): UX Improvement

[hodanoori]

Task Description

The following UX improvements should be applied for the remediation actions.

Acceptance Criteria:

• Image versions in the image details header are displayed as pills instead of plain text
• The actions column in both the active and remediated vulnerabilities tables has no header label and the hamburger menu is right-aligned within the cell
• After performing a false positive or revert action, a spinner appears in the actions cell of the affected row while the API call is in progress — the rest of the row remains visible and the modal stays available for error feedback
• A success message is shown for 10 seconds after a successful false positive or revert, informing the user that status updates may take 5–6 minutes to appear in the tables
• A spacing gap exists between the success/error message and the data grid in the Remediation History panel
