feat(agent): complete instance-chat robustness fixes (Fix 2-6)

Fix 2 — Callback timeout wiring:
- Store callbackTimer in pendingCallbackTimers Map after creation
- handleOpenClawAppCallback clears the timer immediately on arrival,
  preventing spurious "timeout" errors when the bridge replies in time

Fix 3 — Provider scope isolation:
- Override agentStatusProvider and robotStateProvider in child ProviderScope
  so the robot avatar/FAB reflects the instance chat state, not iAgent's

Fix 4 — Voice routing to OpenClaw:
- AgentInstanceChatDatasource.sendVoiceMessage() now calls transcribeAudio()
  then routes the transcript through instance-specific createTask() endpoint,
  ensuring voice messages reach the user's OpenClaw agent, not iAgent

Fix 5 — Attachment UI in instance mode:
- Attachment button shown as disabled (onPressed: null) with explanatory
  tooltip ("附件功能暂不支持智能体对话") when agentName != null
- Prevents misleading UX where attachments appear to work but are silently
  dropped by the OpenClaw bridge

Fix 6 — DB schema template:
- Add agent_instance_id UUID NULL to agent_sessions table in migration 002
  (tenant schema template) so new tenants get the column from creation
- Add covering index idx_agent_sessions_instance for efficient instance queries

All TypeScript and Flutter analyze checks pass clean.
