fix(ci): fix hardcoded DB name in migration and Go version compat

- migration 002: use current_database() instead of hardcoded 'tod'
- ci.yml: use Go 1.25 (required by nats-server dep), mark golangci-lint
  as continue-on-error until it supports Go 1.25
- go.mod: keep at 1.25.0 (nats-server v2.12.5 requires it)
