Replaces hand-rolled <pre><code> blocks across the upgrade-instructions components with Starlight's <Code> so commands get syntax highlighting and a built-in copy button. Also flattens the orphan <ol> in DockerComposeUpgradeSteps so the TB_VERSION block aligns visually with the surrounding command blocks.

Also flattens the orphan <ol> in DockerComposeUpgradeSteps so the TB_VERSION block aligns visually with the surrounding command blocks. * fix(a11y): apply alt text for blog, device-library, rule-nodes, and product images (#424) Update 244 image alt texts from the SEO/accessibility audit (CSV): - 210 blog `` images across 37 posts - 16 `<DocImage>` alts in 4 device-library guides - 7 rule-node icon items in shared _includes; RuleNodeCardGrid now surfaces `item.alt` while keeping `aria-hidden` on the placeholder (alt for SEO, no redundant a11y announce next to title/desc) - 11 product-page images (mobile, mobile-pe, thingsboard-pe, trendz): added optional `phoneSideAlt` to MobileFeatureBlock and `alt` to FeatureCard; wired per-image alts on the pages
