ci: make local e2e the merge gate

[piotr-iohk]

Related to synonymdev/bitkit-e2e-tests#221 (PR B)

This PR:

1. Drops staging jobs from the local merge-gate workflow so required e2e-status is local-only
2. Keeps e2e-staging.yml on schedule and dispatch (no PR trigger)
3. Runs migration on release-* PRs and posts the same Slack summary as staging

Description

Staging stays off the merge gate. Feature PRs no longer wait on stag0. Local lnurl_transfer grep is @lnurl|@transfer_2. Staging shards stay @multi_address_2, @pubky, @hardware_wallet, @transfer_max (@transfer_1 later). Slack checkout uses the resolved e2e-tests branch so a same-named branch can test slack_summary.py.

Migration: pull_request runs only when head or base starts with release-. Slack posts on schedule and on dispatch when post_to_slack is true, using SLACK_WEBHOOK_URL_STAGING.

Automated Checks

• Workflow YAML only. After merge: a feature PR should go green on e2e-status without staging jobs.
• After merge: gh workflow run e2e-staging.yml still works; migration on a release-* PR should run; nightly/dispatch with post_to_slack posts to #bitkit-staging-nightly.

The PR appears safe to merge, although the existing non-blocking concern about executing mutable external references with the Slack webhook remains unresolved.

Summary

This PR makes local E2E tests the pull-request merge gate and expands migration workflow triggering and reporting.

• Removes staging build and test jobs from the local E2E workflow and makes e2e-status depend only on local shards.
• Narrows the local transfer shard to @transfer_2.
• Runs migration jobs for non-draft pull requests whose head or base branch begins with release-.
• Adds scheduled and opt-in dispatch Slack summaries using the resolved E2E test branch.
