fix: move API markdown route to utils to prevent SSR interception (#79)

The catch-all `apis/[...slug].md.ts` route intercepted all `/apis/**`
requests. For non-`.md` paths it returned undefined, which Nitro treated
as empty 200, blocking SSR. Moved to a util function called from the
root `[...slug].md.ts` handler instead.
