fix(bienvenida): bottom-anchor content and add the blurred backdrop
Audit 14.2 (t4 lines 693/706): content was top-anchored in a plain SingleChildScrollView; the prototype anchors it to the bottom with two flexible spacers, so the CTA sits at the screen edge. Restructured as a scrollable Expanded region (safe on short screens / large text scale) with the CTA pinned below it, always at the bottom. Audit 14.1 (t4 lines 687-689): added the full-bleed blurred banner backdrop, reusing aurora_wave_banner.png (the same asset the deleted PluriScreenHeader used) since this app has no bundled equivalent of the prototype's mockup-only banner.jpg. No monetization content touched (PRO pill, "14 días", pricing card, free-version link all remain absent per the binding no-monetization decision).
