Separate status bar bindings from help dialog bindings

Created two separate methods:
- Bindings() - Returns curated subset for status bar (existing behavior)
- AllBindings() - Returns comprehensive list for help dialog

This way the help dialog shows ALL available shortcuts (Ctrl+y, Ctrl+o,
Ctrl+s, Ctrl+m, Ctrl+x, Ctrl+z, Ctrl+b) while the status bar remains
uncluttered and only shows the most essential commands.

Fixes the issue where adding bindings to show in help would also crowd
the status bar unnecessarily.
