fix(blog): real logos on the Bun Rust rewrite cover (#7989)

* fix(blog): use real Bun/Rust/Prisma logos on the Bun Rust rewrite cover

The cover for "We put Bun's Rust rewrite in production on Prisma Compute"
used crude geometric stand-ins for the logos: a flat circle for Bun, a
stretched diamond for Rust, and an asymmetric outline triangle for
Prisma. They read as deformed.

Replace each with the official logo mark (from
apps/site/public/icons/technologies), embedded as a nested <svg> with
its own viewBox and preserveAspectRatio="xMidYMid meet" so they scale
uniformly and never warp. Rust is recolored to the cover's orange and
Prisma to its teal accent; Bun keeps its native colors. Embedded ids are
prefixed to avoid colliding with the cover's gradient/filter ids.

Regenerated meta.png (1200x630) from the corrected SVG.

* fix(blog): replace Bun Rust rewrite cover with the on-brand designed art

The hand-built SVG (geometric/gear logos) still read as off-brand. Swap
it for the finished cover: centered title with "Rust rewrite" in the
brand teal, Bun's logo, Ferris (the Rust crab), and a Compute chip mark
on glowing tiles, with the Prisma wordmark.

- Add hero.png (1600x840) and regenerate meta.png (1200x630) from it.
- Point heroImagePath at hero.png and drop the old hero.svg.
