feat: use keybindings in all selectors and lists

Update all selector/list components to use EditorKeybindingsManager:
- model-selector, session-selector, oauth-selector, user-message-selector
- hook-selector, hook-input, hook-editor, tree-selector
- select-list, settings-list, cancellable-loader

This allows users to configure selectUp, selectDown, selectConfirm,
selectCancel actions in keybindings.json
