Add Lightroom's export and copy shortcuts to develop
Ctrl+E opens an export sheet: the export defaults on their own, over the photograph, with an Export button. Ctrl+Shift+E exports straight away on those defaults. There is no per-export copy of the settings, so what is chosen in the sheet is saved as it is on the settings page, and the next Ctrl+Shift+E uses it. To make that one set of controls in two places, the export options move out of the settings page into export.slint: an `ExportOptions` global that Rust writes once, and two panels that read it. The window no longer forwards forty `settings-*` properties to the page. Ctrl+Shift+C opens a copy sheet with the edit-kind chips the preset sheet already uses and a Copy button, which is how a paste leaves each photograph's crop and rotation alone (Compose off). A and D step along the roll beside the arrows. While either sheet is up the develop keys stand down, so A cannot change the photograph behind the form, and Escape closes it.
