Implements Spec 077 refinements: workspace Global Mode and navigation/context-bar redundancy cleanup.
Summary
- Global Mode: `/admin/workspaces` is workspace-optional (lists only member workspaces); explicit allowlist in `EnsureWorkspaceSelected`.
- Navigation cleanup: workspace switching is topbar-only; no sidebar “Switch workspace”; removes redundant “Manage workspaces” entry from context-bar.
- Context bar: when no workspace selected, tenant picker is disabled with guidance; on tenant-scoped routes `/admin/t/{tenant}/…` the tenant indicator is read-only (Filament tenant menu remains primary).
- Authorization: workspace creation is policy-driven (`WorkspacePolicy::create()`), enforced in `ChooseWorkspace` via Gate.
Safety / Compliance
- Livewire v4.0+ compliant (Filament v5).
- Panel provider registration remains in `bootstrap/providers.php` (no changes required).
- Global search: no new globally searchable resources added; no behavior changes introduced.
- Destructive actions: none added/changed.
- Assets: no new assets registered; deploy process unchanged (if assets are registered elsewhere, ensure `php artisan filament:assets` runs in deploy as usual).
