keyed the dock, header and shell chrome (555 -> 487)

Layout reaches zero. The dock, header, user menu, theme switcher, spotlight,
shortcuts modal, screen-error fallback, rescan and bug report.

Three things worth knowing:

CORE_DOCK_ITEMS now carries labelKey instead of label, and one useDockItems() hook
resolves the composed list. DashboardLayout, Spotlight and DockSettings each spread
the same two sources before, so each would have had to resolve labels itself.
Plugin tiles keep the name from their own manifest — a plugin's strings are not ours.

Spotlight resolves labels INSIDE the hook, so rank() still matches what the reader
can see rather than a dot-path. Its to: '/settings/...' literals are untouched, which
is what docs:check parses — verified still 20 offered, 0 missing.

The rescan toast said 'N skill(s)'. That is English giving up on a plural, so it is
now a real plural entry per noun and reads correctly at 0, 1 and 2 in both locales.

ThemeSwitcher used t as its theme loop variable; renamed to entry.
