feat: forestrie event message additions

* Add the confirmation states representing the forestrie trust levels
as described here:

https://github.com/datatrails/\
  epic-8120-scalable-proof-mechanisms/blob/main/event-trust-levels.md

* Add the provisional extra details we need in the event for the
MERKLE_LOG proof mechanism

* Use a single oneof per proof mech details

fix: the include paths for openapiv2

build: simplify the include path discovery
build: export the proto dependencies under proto-include

This means consumers do not need to replicate the tricky go list
based include path discovery

ci: add a job to check the dockerall task works

But note this is disabled due to acr permissions issues

For people who can't or wont install protoc and go

AB#8859

remove fields that are not settled yet

use oneof for proof_details

 Common public api definitions for the DataTrails platform
 
+## Finding and including proto files for depdendecnies
+
+tools/go.mod is the source of truth for all proto providing dependencies. That file alone specifies both the upstream version we are using *and* is used, via go install, to make the .proto files available locally
+
+This corresponds to the practice recommended by grpc-gateway and elsewhere
+
+1. *** ALWAYS *** Use tools/go.mod to specify the dependency version.
+2. Add the package to the `go install` command in the apis:preflight task
+3. If necessary, add a var for the new path in any-api **and** then add a reference to that var in the PROTO_INC var.
+
+Following this practice removes the need for dual maintenance of dependency versions in the builder image. It also produces a build cycle that is significantly faster.
+
+Cross repository builds in docker while using go.work to refer to locally modified sources don't work. And this setup is essential for an efficient workflow.
+
+## bootstrap proto files
+
+The proto's for protoc itself, the googleapis, and the grpc_health proxy are needed by almost everything and are also don't apear to be compatible with the tools/go.mod approach
+
+For this reason we curl the proto's and make them available in our aggregate proto-includes archive
