IONOS(ci): trigger remote workflow for rc/* and */dev/* branches

Extends three things to handle the newly-buildable rc/* and */dev/*
branches:

1. trigger-remote-dev-workflow's gating condition now accepts
   rc/* and */dev/* refs in addition to ionos-dev/ionos-stable.
2. BUILD_TYPE mapping in the GitLab webhook payload:
   - rc/*    → 'rc'
   - */dev/* → 'dev-<owner-slug>' (matches the Artifactory stage prefix
     introduced in the companion 'route rc/*…' commit so the GitLab
     side can reason about artifact location consistently).
3. The prepare-matrix preflight-summary branch-validity regex now
   matches the same four patterns, so the predicted go/no-go in the
   step summary stays accurate.

GitLab pipeline coordination: the new BUILD_TYPE values land in the
trigger payload's `variables[BUILD_TYPE]`. Coordinate with the GitLab
maintainer to confirm the downstream pipeline handles 'rc' and
'dev-*' explicitly (or accepts them as fallthrough to 'dev'-like
behavior).
