App settings use your browser's date and time pickers, and other improvements

Fixes

• Anthias 2026.07.3 reports itself as 2026.07.3 in System Info. The previous release reported itself as 2026.07.1.

Improvements

• An app setting that holds a date, a time or both, like the Timer app's "Target date & time", opens your browser's date and time picker instead of a text box you had to type an ISO 8601 value into. It's there when you add an app and when you edit one.
• The install guide and the website's get-started page recommend Raspberry Pi Imager for most people. The one-line install script is marked as advanced, and the guide shows how to download it and read it before you run it.
• The hardware table on the website's get-started page lists the Raspberry Pi 3 Model A+ as not recommended: its 512 MB of RAM is too little for Anthias. Pick a board with at least 1 GB, a Pi 3 Model B or newer.

For contributors

• The SBOM workflow adds an SBOM for the website's dependencies, alongside the JavaScript and Python ones, and runs for release tags only. Each SBOM is still uploaded to sbomify and attested, and is now filed under its Anthias release there.
• Dependabot uses the uv ecosystem for Python, so uv.lock is updated together with pyproject.toml, and it no longer proposes Django major upgrades in the grouped Python update.
• Dependencies updated, including yt-dlp and Ansible.
