V56 - UUID Column Consistency Fix + UUID FK Columns

• Adds missing uuid column to phoenix_kit_consent_logs (V43 schema expected it)
• Switches 17 tables from gen_random_uuid() (v4) to uuid_generate_v7() (v7)
• Fixes V55 Comments tables UUID PK defaults (gen_random_uuid → uuid_generate_v7)
• Adds NOT NULL constraint to 11 tables (V43, V46, V53, and uuid_repair.ex core tables)
• Adds missing unique indexes on uuid for 13 tables (V43, V45 Shop + uuid_repair.ex core)

• Adds ~80 UUID FK columns alongside integer FKs across ~40 tables
• Backfills UUID FK values via JOIN from source tables (batched for large tables)

• Prepares for UUID primary key switch in Ecto schemas
• All operations idempotent — safe on fresh installs and all upgrade paths

• Safe no-op on databases where V56 already created everything correctly

V58 - Timestamp Column Type Standardization

• Converts ALL timestamp columns across 68 tables from timestamp to timestamptz
• Completes DateTime standardization (Elixir :utc_datetime + PostgreSQL timestamptz)
• No USING clause needed for up (PostgreSQL treats timestamp as UTC implicitly)
• Down uses USING col AT TIME ZONE 'UTC' for safe revert to timestamp(0)

V60 - Email Templates UUID FK Columns

• Adds created_by_user_uuid and updated_by_user_uuid columns to phoenix_kit_email_templates
• Fixes schema/migration mismatch where Template schema referenced UUID columns never created
• Idempotent: checks column existence before adding (safe for fresh installs where V15 now includes them)
• Resolves fresh install crash at V30 caused by V15 seed query failing on missing columns

V61 - UUID Column Safety Net (V40 Flush Fix)

• Adds missing uuid column to 6 tables that V40 silently skipped due to Ecto command buffering
• Root cause: V40 used repo().query() (immediate) for table existence checks, but V32-V39 table creation commands were still buffered (not yet flushed). V31's flush() was the last flush before V40.
• Tables fixed: admin_notes, ai_requests, subscriptions, payment_provider_configs, webhook_events, sync_transfers
• Also adds created_by_uuid FK column to phoenix_kit_scheduled_jobs
• V40 now includes flush() at start of up() to prevent recurrence on new installations
• All operations idempotent — safe on any installation

V62 - UUID Column Naming Cleanup (_id → _uuid)

• Renames 35 UUID-typed FK columns from _id suffix to _uuid suffix
• Enforces naming convention: _id = integer (legacy/deprecated), _uuid = UUID
• Groups: Posts (15), Comments (4), Tickets (6), Storage (3), Publishing (3), Shop (3), Scheduled Jobs (1)
• No data migration — columns already hold correct UUID values, pure rename
• All operations idempotent (IF EXISTS guards) — safe if module tables don't exist
• PostgreSQL auto-updates FK/index column references; constraint object names are unchanged

V63 - UUID Companion Column Safety Net Round 2

• Adds uuid identity column to phoenix_kit_ai_accounts (missed by V61 due to wrong table name)

• Adds subscription_uuid companion to phoenix_kit_invoices (backfilled from subscriptions)

V64 - Fix user token check constraint for UUID-only inserts

• Drops V16's user_id_required_for_non_registration_tokens constraint (checks user_id)
• Adds user_uuid_required_for_non_registration_tokens constraint (checks user_uuid)

• Drops NOT NULL on user_id for 5 posts tables where schemas only set user_uuid
• Tables: post_groups, post_comments, post_likes, post_dislikes, post_mentions
• Fixes create_group and like/dislike/comment/mention inserts failing with not_null_violation

V67 - Make all remaining NOT NULL integer FK columns nullable

• Drops NOT NULL on 42 legacy integer FK columns across 30 tables

• Converts phoenix_kit_email_logs.uuid to native uuid type if needed
• Re-backfills email_log_uuid in phoenix_kit_email_events (resets stale random UUIDs written by the V56 NULL-fill fallback, then re-runs the proper JOIN backfill)
• Re-backfills matched_email_log_uuid in phoenix_kit_email_orphaned_events
• All operations idempotent — safe on every install
