Packstack: Backpacking Gear

Copy for AI: Grab a text-based overview of your gear list for AI to review. Trip summary images now include every pack on the trip, not just the one you had open. Adding gear is easier to read. Items already in your pack show a green check; items not yet added show an outlined +. Selected and unselected states are clearer, and the "already in another pack" badges are more legible. Hiker profile is edited in place. No more tapping into a separate sheet; open the profile and the form is right there. Fixes and polish: - Recently Added list in Add Gear: swiping no longer opens the item. Swipe to reveal delete, tap to confirm. - Categories: renaming a category near the bottom of the list no longer hides behind the keyboard. - Pack, category and filter tabs are higher contrast and match the rest of the app. - Buttons and selected tabs use dark text for better readability. - "All" is now "All Packs" in the pack selector.
