html_generator.get_html_template now emits a shell (empty fullManifest flagged
__uscg_lazy__, inline_manifest=True restores the old behaviour). New route
GET /config_tester/manifest?session=<name>: compact JSON, weak ETag, 304 on
If-None-Match, gzip, torn-read retry (logic in run_api.load_manifest_for_fetch).
/config_tester/dashboard gets gzip + content ETag. The SPA boots with one fetch
(no more double load), resync is conditional and non-destructive, and
web/dashboard.js asks the iframe to re-fetch (reload_manifest) instead of
parsing data out of the Generator's executed message. Also fixes the dead
session-name regex in dashboard_node.py.
