Pull request overview

This PR adds configurable keybinds for dialog actions in the TUI, allowing users to customize keyboard shortcuts for operations like deleting sessions/stash entries, renaming sessions, toggling model favorites, and opening the provider list. The default for session_rename has also been changed from none to ctrl+r.

Key Changes:

• Added five new configurable keybind options: session_delete, session_rename (default changed), stash_delete, model_provider_list, and model_favorite_toggle
• Updated dialog components to use the configurable keybind system instead of hardcoded values
• Enhanced Keybind.match() and Keybind.toString() utility functions to handle undefined values
