ui.border doesn't apply to some floating windows and signature

[mnpqraven]

⚠️ Please verify that this bug has NOT been reported before.

• [x] I checked all existing issues and didn't find a similar issue

Description

lots of windows, including nvf.settings.vim.lsp.mappings.hover have default border if set in the config:

but nvf.settings.vim.lsp.mappings.openDiagnosticFloat doesn't have borders

and so is signature help (i'm using blink-cmp here)

👟 Reproduction steps

programs.nvf.settings.vim = {
    ui = {
      noice = {
        enable = true;
        setupOpts = {
          lsp.progress.enabled = false;
          notify.enabled = false;
        };
      };

      borders.enable = true;
      illuminate.enable = true;
    };
    utility.snacks-nvim = {
      enable = true;
      # https://github.com/folke/snacks.nvim/?tab=readme-ov-file#%EF%B8%8F-configuration
      setupOpts = {
        bigfile.enabled = true;
        input.enabled = true;
        picker.enabled = true;
      };
    };
  };

👀 Expected behavior

all kinds of floating windows have border

😓 Actual Behavior

ui.border doesn't apply to some floating windows and signature

Note that you can set winborder to get more consistent borders regardless of support in nvf

ok I have no idea why hover is using our custom borders we didn't set it explicitly ._.
