Remove plugins superseded by LazyVim defaults

- mini.indentscope: snacks.indent has scope enabled by default, and the extra
  existed only to disable it in favour of an animation set to 1ms
- nvim-pqf: eagerly loaded and cosmetic; nvim-bqf covers quickfix on ft=qf
- dial.lua: the override replaced the extra's keys and opts, dropping visual
  mode, g<C-a>/g<C-x>, and the per-filetype augend groups
