feat(quick-261022-k9k): Esc, slash and help shortcuts, settings, account and modal save keys

- '?' help dialog (ShortcutHelpDialog) listing the current screen's shortcuts
- Esc = Cancel on record forms; '/' focuses the list search
- settings forms: Save and close (Ctrl/Cmd+Enter, then /settings) and Ctrl/Cmd+S
- My account: Ctrl/Cmd+S
- modal forms: Ctrl/Cmd+S and Ctrl/Cmd+Enter submit the innermost dialog only
- docs: Keyboard shortcuts section in the admin SPA page
