Adds deleted_at and deleted_by columns to trees table for proper soft delete tracking. Supports future 30-day restore window functionality. The delete endpoint now sets both is_active=False (backward compat) and deleted_at/deleted_by. Migration backfills existing is_active=False rows. Fixed ambiguous FK relationship between User/Tree models by adding explicit foreign_keys to both sides of the author relationship. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
