feat(zhipu): support team GLM Coding Plan usage query

Team GLM Coding Plan accounts fail the quota probe with
"当前用户不存在coding plan" because the personal-plan query path
does not carry team context.

- quota probe: when credentials contain zhipu_organization, switch the
  Zhipu quota endpoint to the team variant (?type=2 + bigmodel-organization
  / bigmodel-project headers); personal plans keep the existing path
- account create/edit modals: optional organization/project ID inputs for
  zhipu coding-plan accounts, persisted in credentials; edit modal
  backfills them and clears back to personal plan when emptied
- add a click-to-open tooltip tutorial (zh/en) explaining how to grab the
  IDs from the bigmodel.cn web console via the /api/biz/v1/organization
  network request, with a sample URL mapping org-/proj_ segments to fields
