fix: add idempotency guards to 18 migrations to prevent upgrade failures

When any migration fails due to table/column already existing, PostgreSQL rolls back
the entire batch and blocks all subsequent migrations. Add Schema::hasTable() and
Schema::hasColumn() guards to all problem migrations for safe re-execution.

Fixes #7606 #7625
