fix(zsh): apply keybindings reliably on first startup

- set bindkey -e before custom binds and load zsh/terminfo early
- remove later bindkey -e that reset earlier keymaps
- preserve terminfo application mode hooks

This prevents Ctrl+Arrow and other navigation keys from failing until .zshrc is re-sourced.
