feat(ui): Ghibli/Miyazaki reskin + Obsidian docs vault + project audit

UI: warm daylight design system (Tailwind v4 @theme palette, gh-* component
classes, watercolor grain, Zen Maru Gothic + Klee One fonts), animated SSR-safe
GhibliBackground (drifting clouds, meadow hills, soot sprites), and a full reskin
of navbar, connect button, dapp page, loan cards, settings modal, and readme.
Fixes the bg-white-on-dark loan-card inconsistency. Web3/business logic untouched.

Docs: converted docs/ into an Obsidian vault (frontmatter, [[wikilinks]],
callouts, Home MOC, folders Architecture/Operations/Audits) and added a
full-project audit note (Project Audit 2026-06). Redacted a real leaked Schedy
key value from the security audit example (rotate it at Schedy).

Also commits the previously-untracked server layer: app/api (cron + tasks routes)
and lib (redis, ssrf-guard, task-store).
