feat(admin): add NSFW flag to packs, remove intensity

Re-add is_explicit toggle on pack and dare pack forms labeled as
"NSFW". Show NSFW badge on pack cards and user enabled packs.

Remove all intensity/comfort level references from admin UI including
form fields, analytics charts, review dialog columns, AI generation
prompts/scoring, cherry-pick balancing, and settings toggles. The
database columns remain unchanged.
