fix(wip): WIP - partial unify WeChat/H5 skill prompts (build agent changes)

- Reuse H5's buildAutoChatSkillPrefix in buildWechatAgentPrompt signature
- Inject autoSkillPrefix into voice/text message prompts
- Add origin tagging in GET /sessions for h5/wechat channel labels

Still TODO (will complete in next cycle):
- Full resolveGrantedSkills → buildWechatAgentPrompt flow
- ensureWechatAgentSession idle rotation logic
- setSessionOrigin + touchWechatAgentRoute calls
- Backend schema/migrations (h5_user_sessions origin column)
- Frontend type + UI component updates
