Archive: also cancel open Paperclip issues to clear agent widget

When a case is archived, the legal-ai UI's AgentStatusWidget kept showing
"agents started working, waiting for first report" because related
Paperclip issues remained in 'todo' / 'in_progress' status. Concrete
example: case 1130-25 had two open issues (CMP-15 ניתוח תכנוני, CMP-21
כתיבת החלטה) that lingered after the case was finalized; 1194-25 had
two more (CMP-37, CMP-44).

Extended pc_archive_project to also UPDATE issues SET status='cancelled',
cancelled_at=now() WHERE project_id matches AND status IN
('backlog','todo','in_progress','blocked','in_review'). Returns the list
of cancelled issues so the toast can announce the count.

Updated cases.ts ArchiveResult.paperclip.issues_cancelled type and the
toast message in case-archive-action to surface "(N משימות פתוחות בוטלו)"
when relevant.

Restore is intentionally unchanged — we don't auto-recreate cancelled
issues; if work needs to resume, a fresh issue should be created.

Stale issues for 1130-25 / 1194-25 cancelled directly in DB as a one-off
cleanup (CMP-15, CMP-21, CMP-37, CMP-44).
