feat(sites) : API CRUD + rattachement User<->Site + admin (ticket 2/4)

Exposition de Site via API Platform (5 operations RBAC sites.view/sites.manage),
relation User.sites (M2M user_site EAGER) + User.currentSite (M2O nullable,
ON DELETE SET NULL). Endpoint PATCH /api/me/current-site via ressource
virtuelle + processor (SiteNotAuthorizedException → 403). UserRbacProcessor
etendu avec gardes post-persist : auto-reset si currentSite retire, auto-select
premier site si null + sites non vide.

Page /admin/sites (DataTable + drawer creation/edition + modale suppression).
UserRbacDrawer etendu avec section "Sites autorises". Colonne "Sites" ajoutee
dans la table /admin/users (liste des noms separes par virgule). Sidebar
entree Sites (module: sites, permission: sites.view).

Refactor adresse : split full_address en street + complement (nullable) + getter
computed Site::getFullAddress() multi-lignes. Migration ALTER dediee pour
compat devs ayant deja joue le ticket 1. Fixtures avec vraies adresses
(Chatellerault/Fontenet/Pommevic).

Doctrine : inversedBy synchrone User.sites <-> Site.users pour maintenir la
collection inverse en memoire. User::switchCurrentSite() porte la garde
domaine (throw SiteNotAuthorizedException), aligne sur Role::ensureDeletable.
Helper skipIfSitesModuleDisabled centralise dans AbstractApiTestCase.

Tests : 182/182 (182/182 aussi module desactive, 2 skipped). 29 nouveaux tests
PHPUnit (CRUD API, switch currentSite, cascade DB, /api/me enrichi, extension
/rbac, gardes structurelles fullAddress/currentSite ignores, anti-cycle
Site.users). 11 tests Vitest sur la validation hex couleur.
