Free the Copy URL shortcut from ghost extension registrations (#6821)

* Rebind ghost Copy URL shortcut registrations to the pinned id

Chromium never hands a suggested shortcut to one extension while
another — even a long-gone one — still holds the registration. Profiles
that first loaded Copy URL before its id was pinned registered
Alt+Shift+L under an id derived from the extension's load path at the
time, so the pinned extension never receives the shortcut and the
keypress does nothing (#6816).

The quattro upgrade tried to repair this against one hardcoded
path-derived id, which only ever matched a single home directory. The
historical ids are unknowable in general — they hash long-gone absolute
paths through whatever symlinks existed then — but the registration
itself names the command, so a migration now rebinds any copy-url
command that points away from the pinned id, unless that id belongs to
an extension that is actually installed or the pinned extension already
holds a binding of its own.

Browsers rewrite Preferences on exit, which reverts any repair made
while one runs, so the migration asks for this user's browser windows to
be closed first — failing and staying pending when there is no terminal
to ask in or the prompt is declined. The backup a repair leaves behind
marks it as attempted but unverified: until a browser-free run confirms
the registration stayed repaired, the migration keeps itself pending
rather than trusting a disk state an open browser may still overwrite.

The upgrade-time repair is dropped: the upgrade already runs migrations,
so the migration is the single implementation.

Fixes #6816

* Pin the WhatsApp Slim extension id

Keyless unpacked extensions get path-derived ids, which go stale if the
load path or packaging ever changes — the same class of bug that broke
the Copy URL shortcut for pre-package installs. Pin the id with a
manifest key like the other bundled extensions.
