Three fixes for the collection detail page:
1. Picker modal never showed because the outer overlay div had
style="display:none" with no x-show binding — add x-show bound
to $store.bookPicker.isOpen plus a backdrop and click-to-close.
2. Replace native confirm() with an in-page Alpine modal for UI
continuity. Add confirm dialog state (showConfirm, confirmMessage,
pendingAction) and methods (requestRemoveBook, requestBulkRemove,
executeConfirmed, closeConfirm) to the collections component.
The actual API calls (doRemoveBook/doBulkRemove) are triggered only
when the user confirms.
3. Rename removeBook → requestRemoveBook and bulkRemove →
requestBulkRemove in template + JS renderer so the dialog opens
instead of navigating or failing silently.
