get_case_issues: also match issues by [ערר X] title prefix

The original implementation only returned issues with a plugin_state
linkage (legal-case-number key), which was set just on the initial
setup issue. Sub-agents that created follow-up issues during the case
workflow tagged them in the title ("[ערר 1130-25] כתיבת החלטה" etc.)
but didn't write a plugin_state row, so 23 of 24 historical issues
for case 1130-25 were invisible to the agent activity feed.

Widened the lookup to UNION two paths:
  (a) plugin_state.scope_id matches via the legal-case-number key
  (b) issues.title LIKE '%[ערר {case_number}]%' OR '%ערר {case_number}%'

Used DISTINCT ON (i.id) + post-sort by created_at to dedupe and keep
chronological order. The widget on https://legal-ai.../cases/1130-25
will now show the full history (was 1 issue → now 16).
