Fix takeaway numbers on kitchen displays (develop)

[sridharkalaibala]

Kitchen takeaway tickets showed the sale reference even when an order had a saved takeaway number or token. Include takeaway_number in the desktop query and prefer takeaway number, then token, then the legacy sale reference in both kitchen formatters. Develop counterpart of #1418; excludes unfinished tax audit work.

Validation: 26 kitchen regression tests passed on develop; formatting, packaged-module and attribution checks passed. Both formatters and legacy fallbacks are covered.

Sync: read-only projection of existing branch-scoped sales fields. No persisted data, allocation, gateway or agent changes and no historical renumbering. Live desktop/cloud transport and installer rollout are not verified.

Develop also includes formatting-only fixes in two existing tests flagged by CI. Both suites passed locally (34 tests); no assertions or behavior changed.

Merged to develop. Anyone can test this - you do not need write access.

Try it at https://develop.posnic.io, or run it yourself:

git fetch origin develop && git checkout develop
npm install && npm --prefix api install
npm run dev   # then http://localhost:3000

When you have tested it, say what you did and what happened, and set
QA passed or QA failed. If you cannot set labels, just comment -
a maintainer will.

Reporting that something is broken is as useful as fixing it. It is
better found here than by a shopkeeper.
