Move to workspace:
- movePage() opens a dialog listing all workspaces via /api/workspaces
- doMove(wsId) calls PUT /api/pages/{id}/move with workspace_id
- Updated move API to accept JSON body with workspace_id for cross-workspace moves
Gitea workspace context menu:
- Right-click on any file/folder shows Rename + Delete options
- gwRename() prompts for new name, calls PUT /api/gitea/.../file
- gwDelete() confirms then calls DELETE /api/gitea/.../file
- Both trigger refreshTree() after success
Activity popover:
- 'Edited X ago' timestamp is now clickable (▾ indicator)
- Opens popover showing edited time + created date
