upgrade-2.13-to-2.14

Upgrade a single eRegistrations instance under `Conf-<UPPER_ENV>/compose/<country>/docker-stack.yml` from 2.13 to 2.14, where `<env>` is one of dev/test/preview/prelive/live. This is the largest mechanical step in the chain: bumps every `unctad/<service>:$<VAR>_VER` (or pinned semver) image to `:RC` (the platform tag introduced in 2.14), drops the legacy Keycloak `/auth` path from internal and public URLs across `bpa-frontend`, `bpa-backend`, `camunda`, `mule`, `ereg-cms-frontend`, `statistics-backend`, `statistics-frontend`, renames `MONGO_URI` → `RH_MONGO_URI` on `restheart`, bumps `EREGISTRATIONS_VERSION` and `BUILD_TYPE` to the values the rest of the chain expects (non-dev: `2.14` / `RC`; dev: `DEV` / `DEV`). **Keycloak Quarkus migration is mandatory** — when Wildfly env vars are detected on the keycloak service block, the skill replaces them with the Quarkus block (`KC_DB_*`, `KC_HOSTNAME*`) without prompting; this is a hard requirement of the 2.14 baseline, not an optional cleanup. Conditionally adds an `opensearch-node1` service block plus repoints `GRAYLOG_ELASTICSEARCH_HOSTS` from `$SERVICE_HOST:9200` to `opensearch-node1:9200` when the graylog service still references the legacy Elasticsearch endpoint. Strict mode — aborts on anything unexpected. Env-aware anomaly thresholds. LIVE invocations require a retype-country confirmation rail before commit (skipped in chain mode — the orchestrator does it once up front). Two invocation modes: standalone (creates branch, pushes, opens PR) and chain mode (`CHAIN_MODE=1 CHAIN_BRANCH=<name>`, commits to orchestrator-managed branch, no push, no PR). Swarm-stack (docker-stack.yml) shape only — instances still on docker-compose.yml must run /docker-swarm-migration first.
