fix(luci): ensure Tachyon menu item reliably appears in LuCI

- Remove 'uci: { tachyon: true }' dependency from menu.d/luci-app-tachyon.json so LuCI does not hide the menu node if UCI config is uncommitted/reloading
- Add portable timeout normalization in install.sh ucode to handle Busybox timeout and systems without timeout applet
- Ensure luci_postinst is called directly in IPK postinst (build.sh) and after install in install.sh
- Restart uhttpd alongside rpcd and purge LuCI caches in post-install and uninstaller
- Fix uninstall.sh to remove packages individually with lock retry and omit non-existent luci-i18n-tachyon-en
- In install_ui_packages, verify that menu.d/luci-app-tachyon.json actually exists on disk before proceeding
