refactor(cactus-core): catch block get-open-api-spec-v1-endpoint-base

1. The GetOpenApiSpecV1EndpointBase<S, P> class now has the request
handler migrated to the new error handling mechanism that automatically
differentiates between HTTP statuses of 4xx and 5xx.
2. The register-web-service-endpoint utility function uses the new error
handling utilities as well, but on the lower level, e.g. it coerces unknown
errors to RuntimeError instances to minimize the risk of information loss
when re-throwing the inner exception with more context attached to it.
3. The consensus-has-transaction-finality file was similarly migrated
to the new error handling mechanisms.
4. A dependency to the cactus-core package was added for the easier handling
of HTTP specific errors. The http-errors-enhanced-cjs package contains
useful shorthands for HTTP-aware error handling and can be used in common
JS environments instead of being constrainted to ESM only like the original
library.
