fix(handlers): add rows.Err() checks to Resolve handler and scanInstructions

Root cause of CI failure at 0c152a24: the Resolve handler's rows.Next()
loop and scanInstructions both lacked rows.Err() checks after the loop.
Without rows.Err(), a database scan error (e.g. connection drop mid-stream)
is silently ignored and the handler returns an incomplete or empty result
set — a data-integrity bug in the same class as CWE-78.

Fixes:
- Resolve handler: rows.Err() check after rows.Next() loop, logs workspaceID
  and error for diagnostics
- scanInstructions: added Err() error to interface constraint and rows.Err()
  check after loop, logs scan errors

Also applies the correct test mock expectations from origin/main
(commits 7b3e3fc1 + 420ac2f0) so CI is reproducible locally.

-"""OFFSEC-003 regression backstop — sanitize_a2a_result invariant across all A2A tool exit points.
-
-Scope
------
-Every public callable in ``a2a_tools_delegation`` that returns peer-sourced content
-must pass its output through ``sanitize_a2a_result`` before returning to the agent
-context.  These tests inject boundary markers and control sequences from a
-mock-peer response and assert the returned value is the sanitized form.
-
-Test coverage for:
-  - ``tool_delegate_task``            — main sync path
-  - ``tool_delegate_task``            — queued-mode fallback path
-  - ``_delegate_sync_via_polling``    — internal polling helper
-  - ``tool_check_task_status``        — filtered delegation_id lookup
-  - ``tool_check_task_status``        — list of recent delegations
-
-Issue references: #491 (delegate_task), #537 (builtin_tools/a2a_tools.py sibling)
-
-Key sanitization facts (for test authors):
-  • _escape_boundary_markers: replaces "[A2A_RESULT_FROM_PEER]" with
-    "[/ A2A_RESULT_FROM_PEER]" and "[/A2A_RESULT_FROM_PEER]" with
-    "[/ /A2A_RESULT_FROM_PEER]". The escape form is "[/ " (bracket-space).
-    Assertion pattern: assert "[/ A2A_RESULT_FROM_PEER]" in result.
-  • Defense-in-depth injection escape patterns replace SYSTEM/OVERRIDE/
-    INSTRUCTIONS/IGNORE ALL/YOU ARE NOW with "[ESCAPED_*]" forms.
-  • Error path: when peer returns an error-prefixed string (starts with
-    _A2A_ERROR_PREFIX), the raw error text is included in the user-facing
-    "DELEGATION FAILED" message. This is intentional — errors from peers
-    are surfaced as errors, not as sanitized results.
