Expose every order component as its own entity and prepare for release

Each cost line is now an entity rather than an attribute: subtotal, box price,
add-ons, tax and delivery fee, plus a total and free-delivery-remaining for the
open order, a delivery-day sensor, and a binary sensor that turns off at the
cutoff. Entities share a base class and declare a scope, so a description
states only the field it reads.

Also parses the driver tip, Bounty savings and the free-delivery threshold. The
threshold is carried across orders because the progress bar only renders on
carts that have not met it.

Adds LICENSE, hacs.json, a CI workflow, a pre-publish audit script, and a test
that cross-checks every entity's translation_key against both translation
files. Manifest URLs now point at GitHub rather than a private forge.
