chore(deps): pin tsx 4.23.13 and add migrate:content script

tsx 4.22.4 (the version resolved before this was an explicit
dependency) fails on Node v25.6.1 with "T.registerHooks is not a
function" — its CommonJS-require hook feature-detection finds
node:module's registerHooks but calls it with a shape that version of
Node no longer accepts. This broke both the `payload` CLI (needed for
`generate:importmap`, see next commit) and would have broken
`npm run migrate:content` (MITHOME-87) the same way. 4.23.13 fixes it.
