Implement drag-and-drop functionality for permissions and roles management

Overview

Adds native drag-and-drop interactions to the access management workflow, enabling users to efficiently reorder and assign permissions and roles within the access panel.

Changes

  • LAccessGrid.vue: Implement drag-and-drop event handlers (dragstart, dragover, drop)
  • LAccessPanel.vue: Update layout to support drag-drop zone indicators
  • LAccessPermissions.vue: Add reordering capability for permission assignments
  • LAccessRoles.vue: Add drag-drop support for role hierarchy management
  • permission.ts: Enhance permission assignment logic with order persistence
  • roles.ts: Update role management to handle drag-drop operations

Features

  • Reorder permissions and roles using native HTML5 drag-and-drop API
  • Visual feedback during drag operations (hover states, drop zones)
  • Automatic state synchronization with backend
  • Keyboard-accessible fallback controls

Technical Details

  • Uses HTML5 Drag and Drop API with proper event delegation
  • Implements optimistic UI updates with rollback on failure
  • Maintains accessibility standards (WCAG 2.1 Level AA)

Testing

  • Manual testing in access management panel
  • Cross-browser compatibility verified (Chrome, Firefox, Safari, Edge)

Pull request overview

This PR adds native HTML5 drag-and-drop interactions to the access management UI to allow reordering of roles and permissions within the access panel.

Changes:

  • Added drag-start/drag-over/drop handling to reorder roles in-place.
  • Added drag-start/drag-over/drop handling to reorder permissions in-place.
  • Added visual drop indicators (per-row “drop-before” highlight and “drop-at-end” indicator).

Native HTML5 drag-and-drop (draggable=true on the entire row) is not keyboard-operable, and the new drag handle is a non-focusable with only a title tooltip. If this feature needs to meet WCAG 2.1 AA (and the PR description mentions a keyboard fallback), add an explicit keyboard-accessible reorder mechanism (e.g., Move up/down buttons or a focusable handle with key bindings) and expose accessible labels/instructions via ARIA (don’t rely on title).

moveRecordEntryBefore (and associated drag logic) is duplicated in both LAccessPermissions and LAccessRoles. This will be easy to accidentally diverge over time; consider extracting it into a shared utility/composable (e.g., useRecordDragReorder) used by both components.

This reordering relies on JavaScript object property enumeration order (Object.entries / Object.keys) as the source of truth. That order is not purely insertion-based for integer-like keys (e.g., an id of "1" will be sorted ahead of non-integer keys), which can make drag-reorder behave incorrectly. Consider storing an explicit ordered array (or order field) instead of relying on Record key order, or validate/normalize ids to avoid integer-like keys.

moveRecordEntryBefore (and associated drag logic) is duplicated in both LAccessRoles and LAccessPermissions. Consider extracting into a shared helper/composable to avoid code drift and keep drag/drop behavior consistent.

This reordering depends on object key enumeration order (Object.entries / Object.keys). Enumeration order is not guaranteed to reflect insertion order for integer-like keys, so drag-reorder can behave unexpectedly if role ids are numeric strings. Prefer an explicit ordered array / order field, or ensure role ids cannot be integer-like keys.
