fix: enable bash tool and add GraphQL pagination in firewall-issue-dispatcher

[Copilot]

The optimized firewall-issue-dispatcher workflow instructs the agent to run gh api graphql but never grants execution capability, and the query silently truncates results at 50 issues / 100 comments with no pagination.

Changes

• Enable constrained bash tool — adds bash: ["gh api graphql:*"] to the frontmatter so the agent can actually execute the batch fetch step
• Add cursor pagination — query now accepts $endCursor: String, passes after: $endCursor to the issues connection, and returns pageInfo { hasNextPage endCursor }; command switches to gh api graphql --paginate to fetch all pages automatically

- gh api graphql -f query='
-   query {
-     repository(owner: "github", name: "gh-aw") {
-       issues(labels: ["awf"], states: [OPEN], first: 50) {
+ gh api graphql --paginate -f query='
+   query($endCursor: String) {
+     repository(owner: "github", name: "gh-aw") {
+       issues(labels: ["awf"], states: [OPEN], first: 50, after: $endCursor) {
+         pageInfo { hasNextPage endCursor }

Lock file recompiled and post-processed after frontmatter changes.
