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).
