fix(errors): replace stale roboco_task_* MCP refs in error messages with gateway verbs

10 stale remediation hints across api/routes/tasks.py + exceptions.py pointed at MCP tools deleted in Phase 4 T9 (roboco_task_start, roboco_task_qa_pass, roboco_task_qa_fail, roboco_task_progress, roboco_task_unblock, roboco_task_submit_verification, roboco_task_submit_qa, roboco_task_complete, roboco_task_claim, roboco_task_activate). Each now mentions both the gateway verb (i_will_work_on, pass, fail, complete, unblock, etc.) and the panel REST equivalent. Surfaced live during NAS smoke.
