Drop the product branding: this is just Settings

It is the system settings app for this desktop, so it is named the way
one is. The window is "Settings", the titlebar is "Settings", the
wordmark above the search field is gone, the sidebar's last row is
"About", and the status line reads "Desktop is healthy".

Prose followed the same rule. Forty-odd strings explained what "Panama"
does -- "Panama never animates while idle", "Restore Panama defaults",
"Panama looks in ~/Pictures/Wallpapers" -- which is how a product
describes itself, not how a settings panel describes a setting. They now
say what happens. No user-visible "Panama" remains anywhere in the app.

Two consequences worth naming:

The SUPER+I shortcut's description is user-visible, because the
Shortcuts page is generated from it, so that is renamed too. Rebindings
are keyed by shipped chord rather than description, so no existing
override is orphaned by this.

Three contracts matched the window by title and one matched that
shortcut by description; all four are updated. There are no Hyprland
window rules keyed on the title, so nothing about the window's placement
changes.

The desktop entry is now Name=Settings, but the FILE keeps its
panama-settings name, as does the icon: the dock pins applications by
desktop id, and renaming the file would silently unpin it.
dock-pins-contract covers exactly that.

The dated design docs under docs/superpowers keep the old name. They are
a record of what was decided when, and editing them to agree with the
present would make them lie about the past.
