test: stabilize ESM e2e coverage and suites
Harden element-demo E2E helpers/spec assertions for stable ESM delivery and author validation across phase, baseline, and legacy suites. This locks in stricter runtime-safe checks while reducing flake from element-specific interaction and rendering differences. Made-with: Cursor

## ESM Coverage Status
6+
7+
The current suite is stabilized for **ESM mode** and validates delivery/author usability across in-scope PIE React elements.
8+
9+
- Dedicated interaction phases intentionally exclude: `rubric`, `complex-rubric`, `multi-trait-rubric`, `passage`
10+
- Baseline matrix still validates delivery/author checks for the full registry
11+
- Strict baseline checks enforce:
12+
- route load success for delivery and author views
13+
- visible delivery/configure content roots
14+
- gather interaction attempt
15+
- evaluate-mode signal path
16+
- runtime safety guardrails (with narrowly scoped per-element guards where needed)
