New RLS table jira_issues keyed on (integration, provider, finding uid) that
stores the Jira issue key, URL and last observed status for every finding
sent to Jira. send_findings_to_jira() pre-checks the batch in bounded
chunks, refreshes the status of linked issues in bulk, skips findings whose
issue is still open (reported as skipped_count / skipped), creates a
replacement issue when the linked one is closed or deleted in Jira, and
reserves the slot before calling Jira so concurrent runs cannot duplicate.
Read-only GET /api/v1/jira-issues exposes the links with provider-scoped
visibility. Rows are removed with the provider.
