tags in showcase (vibe-kanban) (#1268)

* Done! I've added the 5th slide for the tags feature:

1. Added the slide configuration in [showcases.ts](file:///private/var/folders/xw/pvvt9zw954zbk1304cvjlnz00000gn/T/vibe-kanban/worktrees/20bc-tags-in-showcase/frontend/src/config/showcases.ts) with the video URL
2. Added English translations for the tags feature in [tasks.json](file:///private/var/folders/xw/pvvt9zw954zbk1304cvjlnz00000gn/T/vibe-kanban/worktrees/20bc-tags-in-showcase/frontend/src/i18n/locales/en/tasks.json)

The showcase now has 5 slides with the tags feature explaining how users can save custom prompts and embed them in tasks or follow-ups.

* Done! Updated the video URL and added translations to all locales:

- Updated video URL in [showcases.ts](file:///private/var/folders/xw/pvvt9zw954zbk1304cvjlnz00000gn/T/vibe-kanban/worktrees/20bc-tags-in-showcase/frontend/src/config/showcases.ts)
