fix(claude-code): add missing Prisma migration for skill marketplaces

schema.prisma had the LiteLLM_SkillMarketplaceTable/marketplace_id/
allowed_skills additions but no committed migration captured them,
failing the schema_migration_check CI job.

Also fix ci_cd/run_migration.py: its temp migrations directory was a
fixed path at <repo_root>/migrations, colliding with the real tracked
migrations/ directory (Dockerfile, run.py) - running the script deleted
it via the cleanup step. Use a real tempdir instead.
