feat: [memory] admin panel Memories tab — browse, search, inspect, de… (#57)

* feat: [memory] admin panel Memories tab — browse, search, inspect, delete

Add 13th admin tab in the Observe group for cluster-wide memory
management.  List view with type/scope filter dropdowns and debounced
search input.  Detail modal shows full metadata grid and scrollable
content block.  Delete from both list row and detail modal with
confirmation and audit trail.

Permission-gated behind admin.memories.  Escape key, backdrop click,
and focus trap wired for the detail modal.  Mobile responsive: hides
description and updated columns below 700px.

* fix: memory detail modal — focus, delete safety, CSS shorthand order

Address Copilot review feedback: move focus to close button on modal
open for keyboard accessibility, disable delete button and clear stale
handler during loading/error states to prevent wrong-memory deletion,
and fix font shorthand/font-size ordering in toolbar filter styles.
