feat: boot TYPO3 13 with site configs and the theme build

- Site configs for the seven live sites from EP/website, Development
  base variants on *-ep13.ddev.site (DDEV additional_hostnames)
- Webpack Encore build moved to the root, output in
  packages/ep_theme/Resources/Public, public path /_assets/<hash>
- Search UI removed from the kept layouts and partials, as the static
  export already does
- Daytrip room selection and the contingent chain removed (contingent
  import is not ported; no daytrip product has current contingents)
- f:uri.action is final in v13: Uri\AjaxViewHelper invokes it
- Remaining QueryBuilder::execute() and array logicalAnd() calls,
  addRootLineFields, TSFE getData, legacy typo3conf/ext template path
- Rector skips the plugin-to-CType rules; plugins stay list_type
