test(handlers): add InstructionsHandler coverage — 18 cases

Add sqlmock unit tests for InstructionsHandler (instructions.go):
- List: empty result, scope filter, workspace_id filter, DB error
- Create: success (global), success (workspace with scope_target), invalid scope,
  workspace scope missing scope_target, content too long (>8192), title too long (>200)
- Update: success, not found (0 rows), content too long, title too long
- Delete: success, not found (0 rows)
- Resolve: empty workspace, with global+workspace instructions, missing workspace_id
- scanInstructions: rows.Err() handled gracefully (continues, not fatal)

All 18 tests cover the DB query paths using sqlmock.
