refactor(layout): extraire le magasin d'injection vers shared-wallet/bootstrap

L'entrée publique `/polyfill` portait le magasin d'injection (le `ng` injecté,
les dépendances du registre, QUI est connecté, le singleton `CapRegistry`). Tout
module interne l'importait donc pour atteindre la config — ce qui faisait de
l'entrée une dépendance du code qu'elle publie, avec les cycles
`polyfill` <-> `connect` et `polyfill` <-> `inbox`.

Le magasin rejoint `shared-wallet/` : rien n'est injecté en amont, l'app importe
le SDK et « qui suis-je » est la session — il n'y a pas de relais d'utilisateur
courant parce qu'un wallet a exactement un user. Ce module est la forme de cette
absence, il s'évapore en entier à la migration.

L'entrée ne fait plus que ré-exporter. Plus aucun module interne n'importe
`polyfill`.
