Subject: [PATCH] fix: wire parentId query filter into issues list endpoint
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The parentId parameter on GET /api/companies/:companyId/issues was
silently ignored — the filter was never extracted from the query string,
never passed to the service layer, and the IssueFilters type did not
include it. All other filters (status, assigneeAgentId, projectId, etc.)
worked correctly.

This caused subtask lookups to return every issue in the company instead
of only children of the specified parent.

Changes:
- Add parentId to IssueFilters interface
- Add eq(issues.parentId, filters.parentId) condition in list()
- Extract parentId from req.query in the route handler

Fixes: LAS-101
