feat: vim nav in wofi, bemoji, clip picker, webcam glyph fix

- wofi config: key_up/key_down accept Up,k / Down,j; Ctrl-u/Ctrl-d for
  page jumps. Picker scripts auto-load this since they only pass --style.

- waybar webcam glyph: U+F0D5D (camera/photo, looked Instagram-y) ->
  U+F0567 nf-md-video (handheld video camera).

- Clipboard picker migrated from fuzzel to wofi for consistency with the
  notification picker. New driver dot_config/waybar/clip-picker.sh:
    pick   (Mod+p)        Enter pastes, Alt-d deletes
    delete (Mod+Shift+p)  Enter deletes
  No clipboard "read" indicator: Wayland has no API for observing reads.

- Emoji picker: bemoji on Mod+period, driven through wofi (so vim nav
  applies there too) and configured to type + copy via wtype.

- LibreWolf flatpak: --device=all override so v4l2 webcams work. Flatpak
  has no finer-grained device flag.

- KEYBINDS.md updated: Mod+p / Mod+Shift+p now describe wofi behavior;
  Mod+period documented.
