Feature/UI action console

[charmi-reddy]

Improves the Action Console UX and reliability for permission handling.

• Reworked permission item state tracking to use action IDs instead of list indexes, preventing state drift when items reorder or refresh.
• Added per-action processing state to avoid duplicate approve/deny requests while an update is in progress.
• Added safe API failure handling with inline retry-friendly error messaging instead of silently failing.
• Switched pending permission counter updates to a functional state update to avoid stale-state race conditions.
• Improved accessibility and usability with labeled feedback input, explicit button types, and clearer action text.
• Cleaned up wording for better readability in the approval/denial flow.

Result:
The Action Console is more stable under real-time updates, clearer for users, and safer during permission status changes.
