feat: launcher to the DP-1 centre, hamburger for English

The launcher sat in the centre of the DP-3 status bar, which is the narrow
rotated screen. It moves to the middle of the DP-1 desktop bar, where the
workspaces and the window list already live and there is room either side of
it. Each bar object carries its own include list, so the module definition
moves with it.

English gets the hamburger back. The stock bar drew it with an emoji, which
this module cannot do: it is an image module and takes a path, not text. So
the emoji ships as an image instead, from Twemoji. Doing it the other way
round, reverting to hyprland/language and its format-en text, would have
brought the burger back at the cost of turning the Italian flag into an emoji
too, and the real flag asset is worth keeping.

flag-gb.svg had no reference left after that, so it is deleted, and install.sh
removes the copy an earlier install left behind.

The docs carried three claims that were wrong rather than merely stale: the
launcher was listed as a CSS background when it has been an image module since
the mark was fixed, and SPEC still described the udt role work as adding roles
named after this bar's modules when what shipped was deleting eleven roles
nothing read. The dot colours were described as coming from [state] roles that
gen_waybar never emitted.

 This repo is a **consumer** of udt: it holds the bar, udt holds the colours.
 
 `styles/theme.css` is generated by `udt-palette` and gitignored, exactly like

-the udt side:
-
-**A new `[waybar]` role block.** The current one names `temperature`,

-The new roles are `launcher`, `workspaces`, `vmdots`, `taskbar`, `volume`,

-`hover_*` and `outline`.
-
-**Added to all nine `roles-*.conf`.** `udt-palette --selftest` enforces that
-every scheme defines the same role set, so a role added to one file and not
-the rest fails the check. That is the check doing its job.

-Dot colours come from the existing `[state]` roles: `success` for a running
-VM, `warning` for paused, `critical` for crashed, `info` for saved, and
-`fg_faint` for shut off. Both dot scripts currently hardcode `#30D158`,

+every other generated file in that repo. udt's `install.sh` writes it straight
+into `~/.config/waybar-udt/styles/theme.css` under a fixed name this bar
+imports, so switching scheme rewrites the file the running bar already reads.
+
+**The `[waybar]` role block has no per-module colours.** This was planned as a
+rename, and turned out to be a deletion. The stock bar alternated module
+backgrounds so it read as stripes, and carried a role for each: `workspaces`,
+`temperature`, `memory`, `cpu`, `time`, `date`, `tray`, `volume`, `backlight`,
+`battery`, plus `charging`. This bar draws every pill on `@main-bg`, and its

+So all eleven module roles had no consumer, and adding `launcher`, `mail` or
+`present` roles would have invented more of the same. They are gone from all

+that actually references it.

+**Dot colours do not come from `[state]`.** `gen_waybar` never emitted
+`success` or `info`, so `install.sh` reads `green`, `teal`, `mauve`,
+`overlay0`, `warning` and `critical` back out of the generated stylesheet and
+writes `~/.config/waybar-udt/dots.colors` for the two scripts to source. They
+are bash and cannot read `@define-color`; both fall back to Macchiato values
+when that file is missing, so they still run standalone.
