chore(frontend): regenerate schemas/types/openapi after the amneziawg trim

npm run gen, matching CI's own codegen check: picks up the updated
ServerSettings/Instance doc comments (types.go) and drops ensureAction
(the old kernel-module Manager's now-deleted internal enum, which
tools/openapigen was scanning and emitting bindings for even though it was
never meant to be part of the public API surface).
