Fix completed progress notification dismissal

[Dhinesh Ponnarasan (DhineshPonnarasan)]

Fixes #314963

Summary

Completed progress notifications could remain visible but non-dismissible in Notification Center:

• the row close action did not reappear
• Clear All Notifications stayed disabled
• notifications.clearAll and the focused-notification clear command skipped them
• the notifications status indicator continued treating completed work as active

Fix

• Preserve hasProgress as progress-handle presence so progress notifications retain their existing deduplication behavior.
• Add active-progress state for UI affordances, stickiness, status, and dismissal commands.
• Refresh Notification Center and toast rows only when progress transitions between active and inactive, covering late starts, completion, and restart without redrawing every progress increment.
• Add model and browser regression tests for activity transitions, completed-progress uniqueness, close-button visibility, and Clear All enablement.

Validation

• npm run typecheck-client
• node build\hygiene.ts <8 changed notification files>
• scripts\test.bat src\vs\workbench\test\common\notifications.test.ts src\vs\workbench\test\browser\notificationsList.test.ts — 14 passing
• Live Code OSS dev-host validation:
  • active progress: progress bar visible, row close action hidden, Clear All disabled
  • completed progress: progress bar hidden, row close action visible, Clear All enabled
  • restarted and re-completed progress: affordances transitioned correctly in both directions
  • Clear All removed the completed notification

Pull request overview

Fixes a workbench notifications UX bug where notifications that previously showed progress could become non-dismissible after progress completion, by treating completed progress as inactive and forcing a row refresh at the completion transition.

Changes:

• Update NotificationViewItem.hasProgress to return false once progress is done().
• Refresh notification list rows in Notification Center and Toasts when progress transitions to completed so close/clear affordances re-render.
• Add regression coverage for hasProgress/sticky semantics and Notification Center clear affordances; document the done() terminal contract.
