feat(cli): list keybindings from key tables

- Display keybindings grouped by their source table, with table name as prefix
- Sort default bindings before table bindings, maintaining visual hierarchy
- Support keybindings defined in key tables alongside default bindings
- Enable users to discover all available keybindings across the entire config
