fix: add missing publishedAt dates to 11 blog posts (#804)

These posts were added 2026-03-06 but never got publishedAt frontmatter,
causing them to be silently excluded from the /blog index page (which filters
on frontmatter.publishedAt). They are now:
- Visible on /blog index
- Included in archive page (already was — archive has no date filter)
- Properly dated for SEO canonicalization

Affected: birdeye/nicejob/podium alternatives, yoga/restaurants/cleaning/
