fix: replace curl with wget in all workflow healthchecks

- Replace curl with wget in healthcheck commands (curl not available in ChromaDB container)
- Fix nightly workflow to use curl from runner instead of docker exec
- Update all action versions from v5 to v4 (v5 doesn't exist)
- Fixes container initialization failures across all workflows
