feat(mui): consistent staggered page entrance across all 43 route pages

Adopt the PageEnter wrapper as every page's outermost render element and remove the ad-hoc per-page entrance motion.div wrappers. Every page now enters the same way — all top-level sections rise+fade in, staggered — so nothing appears instantly and the motion is identical app-wide. Presentation-only: no data/logic/hooks/invalidate/permissions touched. Embedded sub-tabs (CompanySettings, ReceivedInvoices), Login (auth shell) and the dev UiKit are intentionally excluded. Gates: tsc -b --noEmit=0, build=0, vitest 152/152.
