ci(l1): pin assertoor playbook URLs to pre-refactoring commit (#6238)

## Summary

Pin all assertoor playbook URL references from `refs/heads/master` to a
specific commit (`c35b5c3a5f`) — the last `master` commit before
ethpandaops/assertoor PR #137 (major refactoring) was merged.

## Motivation

Since Feb 19 ~17:26 UTC, the assertoor upstream merged a [major
refactoring](ethpandaops/assertoor#137) that
introduced breaking changes:
- `stopChildOnResult` removed (tasks now self-complete)
- `failTaskCount` / `succeedTaskCount` replaced with `failureThreshold`
/ `successThreshold`
- Transaction submission engine replaced with spamoor

Since our configs fetched playbooks from `refs/heads/master`, every CI
run after the merge fails the **Blob & Stability Check** — including
runs with zero code changes.

## Changes

Pinned 4 playbook URLs across 3 files:
- `network_params_blob.yaml` — `blob-transactions-test.yaml`
- `network_params_tx.yaml` — `eoa-transactions-test.yaml`
- `network_params_ethrex_multiple_cl.yaml` —
`blob-transactions-test.yaml` + `eoa-transactions-test.yaml`

## Note

Pinning the playbook URLs may not be sufficient on its own — if Kurtosis
is also pulling the latest assertoor Docker image (with the new
runtime), the old playbooks may still be interpreted differently. We may
also need to pin the assertoor image version in the network params
configs.
