feat(registry): add Maxicode (^BV) 2D barcode support - #102

Maxicode is the UPS shipping symbology — fixed-physical-size, mode-
parameterised 2D code. ZPL ^BVa,b,c,d encodes orientation, mode,
and structured-append indices.
This change adds:
- registry entry with content, mode (2..6), rotation; no module
magnification since the printer always renders the canonical
physical size (heightLocked, no commitTransform)
- bwip-js mapping + maxicode-specific buildBwipOptions case so the
canvas renders the hexagonal bullseye preview
- getDisplaySize case that converts the bwip bitmap back to stage-
px instead of falling through the default (cw, ch) branch, so
the bbox matches the printed dimensions
- parser BV handler with the same fixed-size shape; clamps an
out-of-range mode value to the safe default 4
- per-line palette label + properties strings via the locale
script for all 32 locales (en/de curated, others get a
Maxicode-as-proper-noun + English mode label fallback)
- emit + roundtrip tests
Structured append (multi-symbol composition via SCM modes 2/3) is
parsed but the editor pins emit to (1, 1), since we don't surface
SCM authoring yet.

Code Review
This pull request introduces support for Maxicode, a fixed-physical-size 2D barcode symbology. It includes the registry definition, ZPL generation and parsing capabilities, localization updates across multiple languages, and a dry-run validation helper using an unattached canvas. The review feedback correctly points out a critical issue where validateMaxicodeBwip could cause a server-side rendering (SSR) crash because it accesses document without verifying if the environment is a browser.
