feat(extensions): add bulk extension clearing controls

[reachjalil]

Summary

Adds a My Extensions danger-zone flow for clearing installed extension resources in bulk.

• Adds destructive controls under My Extensions → Advanced settings, not Marketplace.
• Requires GitHub-style typed confirmation before clearing resources:
  • type the current workspace name for this workspace
  • type all workspaces for all workspaces
• Reuses the existing single-item uninstall/remove paths for the current workspace so bulk clearing behaves like uninstalling each extension one by one.
• Adds all-workspaces clearing through each workspace endpoint for skills, cloud plugins, MCP entries, and removable plugins.
• Refreshes extension surfaces after clearing and reports partial failures when some workspaces cannot be cleared.

Validation

• pnpm --filter @openwork/app typecheck
• Manually verified the flow in the desktop UI before moving the changes to this clean branch.
