fix: align local migrations with deployed Supabase state

Rename migration files (039-052) from sequential to real deployed
timestamps, add 11 missing migration files that were applied directly
to production, apply invoice_delivery_note_sequences migration, and
rename placeholder files for clarity.

+**Location**: `supabase/migrations/` — 63 files. Early migrations use sequential numbering (`20240101000001`–`20240101000038`), later ones use real timestamps (`20260223150836`+).
+**Next migration**: Use `mcp__plugin_supabase_supabase__apply_migration` which assigns timestamps automatically.
 
 ### Placeholder Migrations
 
 Some migrations are no-op placeholders to preserve the numbering sequence:
-- **012** (`tax_codes`) — Planned but never deployed. The system operates without the `tax_codes` table.
-- **023** (`document_version_chain`) — Planned but never deployed. Document versioning columns/functions do not exist in production.
