Alexander Brown d2358c83e8 test: extract shared subgraph E2E test utilities (#10629) ...

## Summary

Extract repeated patterns from 12 subgraph Playwright spec files into
shared test utilities, reducing duplication by ~142 lines.

## Changes

- **What**: New shared helpers for common subgraph test operations:
- `SubgraphHelper`: `getSlotCount()`, `getSlotLabel()`, `removeSlot()`,
`findSubgraphNodeId()`
  - `NodeReference`: `delete()`
- `subgraphTestUtils`: `serializeAndReload()`,
`convertDefaultKSamplerToSubgraph()`, `expectWidgetBelowHeader()`,
`collectConsoleWarnings()`, `packAllInteriorNodes()`
- Replaced ~72 inline `page.evaluate` blocks and multi-line sequences
with single helper calls across 12 spec files

## Review Focus

- Behavioral equivalence: every replacement is a mechanical extraction
with no test logic changes
- API surface of new helpers: naming, parameter types, placement in
existing utility classes
- Whether any remaining inline patterns in the spec files would benefit
from further extraction
