feat: trash (soft delete) with admin tool management

- tools: add deletedAt/deletedBy, soft delete via DELETE /tools/:id when
  actor has trash entitlement, else immediate hard delete
- trash endpoints: GET /tools/trash, POST /tools/trash (admin bulk),
  POST /tools/trash/restore, DELETE /tools/trash, POST /tools/trash/empty
- trash feature for premium/enterprise; exclude trashed from all public
  surfaces (browse, categories, features, tags, similar, ratings, costs,
  analytics, redundancy)
- TRASH_RETENTION_DAYS env (0 = keep forever) with hourly purge job
- frontend: /trash page (premium+, restore for all, permanent delete +
  empty for admin), admin Tools tab with multi-select bulk trash,
  sidebar Trash link, tool-detail delete hint
