Refresh screenshot galleries and repair portal upgrades

Use the September 30 hero on the website and README, add a shared screenshot gallery, and remove the old showcase images. Build image links locally and clean generated site output. Back up the known development portal override during installation and report custom overrides before building. Keep source selections clear while letting blur show through unselected rows.
