📄 Description

Fixes : https://github.com/open-webui/open-webui/discussions/24258

Non-admin GET /api/v1/prompts/tags went through get_prompts_by_user_id, which loaded every active prompt with its full content/data/meta plus owner records and all access grants, then ran one has_access query per prompt that wasn't owned by the caller - all so the endpoint could collapse the result to a sorted tag list. With 600 prompts this took several seconds while the admin path (a single SELECT) returned in <1s.

Add Prompts.get_tags_by_user_id which selects only the tags column and applies the same EXISTS-based access filter used by /list. Also tighten the admin get_tags to project just the tags column instead of full rows. The endpoint is now one DB query (plus one for groups), no row hydration, no N+1.
