Extract trust-all SSL logic into buildTrustAllRestTemplate() helper.
Add @Profile("prod") bean that also trusts self-signed certs.
Change @Profile("!local") to @Profile("!local & !prod") so standard
strict SSL is only used for CI/test profiles.
Rename portainerRestTemplate() to portainerRestTemplateDefault().
