release: sync main with dev (about editor, journal template, icon cleanup) (#449)

Brings `main` up to `dev` after #448 realigned the two branches.

`main` had #431 (portfolio features) but was missing everything that
landed on `dev` since:

- #443 — journal sample story ships as a template, not a live entry
- #445 — last emojis in the public frontend replaced with SVG icons
- #446 — About page toggle + content editor in the admin (@lancetm714's
work, rebased)
- #448 — the merge of `main` into `dev`, resolving the `Icons.tsx` split
and porting `IconEyeOff` into the shared icon file

After this merge both branches carry the same tree. CI on #448
(type-check + tests) passed on the merged state.
