fix: restore runtime dependencies incorrectly demoted to devDependencies

PR #33936 removed duplicate dependency entries, but in two cases moved
deps from dependencies to devDependencies that are still re-exported in
the published API reports:

- @backstage/catalog-client: @backstage/plugin-catalog-common
  (AnalyzeLocationRequest/AnalyzeLocationResponse types)
- @backstage/frontend-plugin-api: @backstage/config (Config type)

These need to be runtime dependencies so consumers can resolve the
types at build time.

+Moved dependencies that are re-exported in the public API from `devDependencies` to `dependencies`. These were incorrectly demoted in #33936 because the source code only uses type imports, but the types still appear in the published API surface and need to be resolvable by consumers at build time.
