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.

+Photos are referenced by their Immich asset id, and those ids are specific to
+your server, so this template ships without any. Add them in the studio via
+Add Block → Photo, where the picker fills the id in for you. Written by hand it
+is `![<asset-id>:fullbleed](Caption)` for a single photo — `:wide` or no suffix
+give the narrower widths — and `![<asset-id>, <asset-id>](Caption)` for a
+side-by-side pair.

 # Into the Wilderness
 
 The journey began at dawn along the F-roads winding deep into the interior. As civil infrastructure faded behind us, the landscape shifted dramatically into vast fields of black volcanic ash framed by vivid neon-green moss.
 
 > Silence in the highlands isn't just the absence of sound — it is a physical weight that fills every horizon.

 ### Reflection & Light
 
 As light broke through the storm clouds late in the afternoon, the contrast between the dark terrain and glowing peaks created a surreal atmosphere that felt entirely unearthly.
