File list: h/l and arrow keys do not page (paginator KeyMap is empty)

Describe the bug In the file list, the footer says h/l ←/→ page, but none of those four keys change the page. j/k move the cursor fine. Paging works only with the undocumented f/d and b/u (and g/G for first/last), which the ? help does not list either.

Setup

• OS: macOS 27.0
• Shell: zsh
• Terminal Emulator: Warp
• Terminal Multiplexer: none
• Locale: en_US.UTF-8
• glow 3.0.0 via Homebrew

To Reproduce

1. Run glow in a directory with more documents than fit one screen (mine shows 94, seven pagination dots).
2. Press → or l. Nothing happens.
3. Press f. Next page.

Source Code As far as I can read it: ui/stash.go builds the paginator as a struct literal, paginator.Model{Type: paginator.Dots}, so KeyMap stays the zero value and the paginator's own key handling in Update matches nothing. f/d/b/u still work because glow handles them in its own switch a bit further down in the same file.

Expected behavior h/l and ←/→ page, as the footer says. paginator.New(paginator.WithType(paginator.Dots)) (or assigning paginator.DefaultKeyMap()) should restore them. Happy to send a PR if you want one.

Additional context The ? help view lists the same broken keys and omits the working ones.
