Fix asset cache-busting — include base.css and base.js in ASSET_VERSION

Previously only dashboard/ticket assets were tracked, so changes to base.css
and base.js were never reflected in the cache-busting version string. Browsers
served stale cached copies, meaning the header padding-top fix never reached
users. Touch base files to bump mtime and force a cache miss immediately.
