edit title and text colors

i want to give the box a custom look and change the following:

- [x] make border pink
- [x] make background transparent
- [ ] make main text pink
- [ ] make other text light blue or something

currently have the following config:
```lua
config = function()
require('fidget').setup {
notification = {
window = {
normal_hl = '',
winblend = 0,
border = 'rounded',
border_hl = 'FidgetBorder',
relative = 'win',
},
view = {
stack_upwards = true,
icon_separator = ' ',
group_separator = '---',
group_separator_hl = 'Comment',
},
},
}

-- change colors
vim.api.nvim_set_hl(0, 'FidgetBorder', { fg = '#f0a4d0', bg = 'NONE' })
vim.api.nvim_set_hl(0, 'FidgetTask', { fg = '#f0a4d0', bg = 'NONE' })
vim.api.nvim_set_hl(0, 'FidgetTitle', { fg = '#f0a4d0', bg = 'NONE' })
end
```

`FidgetBorder` is working but the other two aren't

Start with the notification configuration and the FidgetTask and FidgetTitle highlight names shown in the report. Trace where those highlights are used for notification text, then verify that the main and secondary text colors change while FidgetBorder remains pink.
