Fix popover: show all accounts with per-row bars and a dark window

The native tooltip never rendered. Two waybar quirks stacked:

1. custom/ocd had tooltip-format set. For a custom module with
   return-type json, a tooltip-format overrides the JSON tooltip field
   and waybar falls back to the label text (Waybar #3022). So the
   popover showed the single rotating account label instead of all
   accounts. Remove tooltip-format; waybar now uses the daemon's
   JSON tooltip field.

2. The daemon joined tooltip lines with newline. waybar custom
   modules break on newline (the tooltip vanishes; Waybar #3153). The
   wiki says to use carriage return instead. Switch the separator to
   \r.

Reformat the tooltip so each limit (5h/1w/1m) is on its own row under
the account, with a blank row between accounts for a bigger gap, as
requested.

Add a dark tooltip background. waybar scopes tooltip CSS globally
(wiki / PR #4930): style all bar tooltips with the existing theme
dark color @background/@foreground so the popover matches the bar
instead of rendering backgroundless.
