improvement(emails): size the header wordmark to the landing navbar's rule (#6648)

* improvement(emails): size the header wordmark to the landing navbar's rule

The email header rendered the wordmark at 34px of ink against 16px body
copy, and inked it #1a1a1a while every other line of the email uses
#434343.

Size it by the rule the landing navbar states: the mark stands 2px above
and below its neighbouring text (18px against 14px chip labels), so 20px
against the email's 16px body copy. Rasterize it from the same brand
outlines the navbar renders, filled with the email's own textBody token,
so the two surfaces cannot drift.

* chore(emails): drop the wordmark generator script

The raster is committed at 4x, so the display box can be retuned without
re-exporting it — the script only ever ran by hand, and the test pinning
the asset to an exact multiple of the box would have forced a pointless
regeneration on any size tweak.

Keep the shared outlines the navbar and 8 other surfaces already render,
record how the asset was produced on the size constant, and assert the
property that actually matters: the asset out-resolves its display box.

* chore(branding): re-export the branding barrel through the absolute alias

Matches the repo's absolute-import rule and the majority of lib barrels
(billing, table, uploads and five others), instead of leaving this file
split between relative and absolute re-exports.

* docs(branding): correct the wordmark comments that named the removed script

Two TSDoc blocks still pointed at scripts/generate-email-wordmark.ts as
how the email raster is produced. Point them at the committed export and
the size constant that records its fill and scale instead.
