Subject: [PATCH] feat(perf): defer heavy columns in issue deduplication
 queries

Optimizes `create_issue` and `get_nearby_issues` endpoints by deferring the loading of `action_plan` (JSON text), `image_path`, and `location` columns.
This prevents fetching large amounts of unused data during spatial deduplication and list retrieval, reducing memory usage and database I/O.
Verified that deferred fields are not accessed in the response path, preventing N+1 query regressions.
