refactor(wezterm): remove unused pane rotation keybinds

Remove PageUp/PageDown pane rotation keybinds that don't align with wezterm workflow. The static pane layout approach (fixed splits + zoom toggle) doesn't benefit from rotation like dynamic window managers do.

Also update CLAUDE.md to clarify that Home Manager is a NixOS module, so just build/switch commands handle both system and user configurations together.
