Beard Bros Dumpsters 1.0.7 - Calendar Overhaul & Mobile Cleanup

This release modernizes the app end to end: Ruby 4.0.1 and Rails 8.1.2 are pinned, the rentals calendar now uses dumpster emojis with a clearer legend, phone CTA, and Sunday week start, and the overall UI is refreshed with shared styling variables for a consistent mobile-first feel. The dashboard and rentals workflow also got upgraded with explicit emoji selection (no more title hacks), plus cleaner guidance for admins. The result is a cleaner, faster, and more usable site without changing how the core features work.
