* fix(webapp): guard Flux viewer against js-yaml 5.x empty-input throw

js-yaml 5.x changed load('') to throw a YAMLException ('expected a
document, but the input is empty') instead of returning undefined (see
js-yaml migrate_v4_to_v5). The Flux Topology Viewer calls
parseAndRender() on page load while the textarea holds only a comment
(# YAML Definition), so jsyaml.load() now throws before the existing
if(doc==null) guard, surfacing as an uncaught exception that fails the
cypress-e2e suite (flux-page.cy.js).

Wrap the load in try/catch and treat empty/comment-only or malformed
input as 'no document'. Also broaden cypress-tests.yml to run on 2.x so
this class of webapp regression is exercised there too (2.x already
shipped js-yaml 5.2.0 and carries the same latent bug).
