fix: add spacing before Admin link in blog template

[Cozmocat]

The Admin link currently renders directly after the final navigation item as PostsAdmin.

This adds spacing before the Admin link in the blog template while preserving the existing mobile layout.

The change is made in theme.css so it can flow to the Cloudflare template through the normal template sync.

This is the right minimal fix for the stated layout problem. In templates/blog/src/layouts/Base.astro the .nav-admin link is a flex sibling that sits directly after .nav-right, so it renders flush against the last nav item. Adding margin-inline-start: var(--spacing-5) via CSS separates it cleanly while using an RTL-safe logical property, and the existing mobile media query already resets margin-inline-start: 0, so the mobile layout is preserved.

I verified the target class exists in both blog templates, that --spacing-5 is defined in tokens.css, and that this change is CSS-only so no changeset or Lingui update is needed. I did not run the test suite, linter, or formatter.

Two things to address before merge:

1. Formatting — the new CSS is indented with spaces; this project uses tabs everywhere and pnpm format is part of the pre-PR checklist. Run the formatter on templates/blog/src/styles/theme.css.
2. Cloudflare variant — templates/blog-cloudflare/src/styles/theme.css still lacks the rule. Either apply the same addition there or run ./scripts/sync-cloudflare-templates.sh so the checked-in Cloudflare template is actually fixed, as the PR description implies.

[needs fixing] The new .nav-admin declaration is indented with two spaces, but the project convention (and .oxfmtrc.json / .prettierrc) is tabs. The whole file is currently spaces, so run pnpm format to convert it rather than committing more space-indented CSS.

Suggested change

	margin-inline-start: var(--spacing-5);
	.nav-admin {
	margin-inline-start: var(--spacing-5);
	}

[suggestion] This fixes templates/blog, but templates/blog-cloudflare/src/styles/theme.css still has no .nav-admin spacing rule at the PR head. Since the description says the change should flow to the Cloudflare template, either run ./scripts/sync-cloudflare-templates.sh now or apply the same .nav-admin { margin-inline-start: var(--spacing-5); } addition to templates/blog-cloudflare/src/styles/theme.css so the checked-in variant isn't left with the original spacing bug.
