Bottles now have their own page, plus a reorganized edit form

Opening a bottle's own page now shows the full item, ready to edit right there - no more popping open a separate window for it. The edit form itself (both there and everywhere else it still opens as a window) shows the full photo next to a cleaner, better-organized set of fields grouped by what they describe, with more fields hidden until you need them. Search boxes, dropdowns, and toggles across the app were also rebuilt for a steadier, more consistent look and feel.
