• Every app (Tasks, Agenda, Pages, Boards, Bookmarks, Journal, Files, Spending, Goals, People, Recipes and meals, Tidy, Trips) can be turned on or off. Home and Spaces always stay.
• The sidebar shows one section with Home and your enabled apps in your order, then Spaces. The Features section is gone. The phone tabs, the More page and search follow the same list.
• A new settings Apps tab has a toggle per app and up/down buttons to reorder. Routes of disabled apps redirect there.
• Trash is now a settings tab at /settings/trash, and /trash redirects to it. The tabs are ordered Profile, Apps, Security, Developer, Your data, Trash.
• Space pages no longer have the back chevron, matching the other sidebar pages.
• The page tree stays mounted while the sidebar is collapsed, so items don't pop in and out.
• New and Add actions use the medium size, and the quick-add button matches its field's height.

Migration (approved), 20261028000000_apps_as_features: users.features becomes the ordered list of enabled apps. Every core app is prepended in today's order ahead of the extras each user already had, and the default becomes the core list.

Checked in the dev stack: the migration applied, toggling and reordering update the sidebar, /trash redirects, and the space header and collapsed sidebar look right.
