feat: unified THE FORGE // SECTION headers and merged proxy routes

UI consistency
- ForgeHero now supports backHref, mono kicker, stats snippet, staggered
  entrance animation, and a registration-tick divider
- Every route now opens with the same "THE FORGE // SECTION" eyebrow: projects,
  sites, stacks, proxies, events, dns, deploy, settings, stale containers,
  site/project detail + env/volumes/browse, new site wizard
- Stacks list/detail/new moved to the shared hero and brand-anchor eyebrow
- Toolbars migrated from bespoke buttons to the shared .forge-btn utilities
- Sidebar footline adds a live UTC "forge clock" and a vim-style g-prefix
  quick-nav hint (g d/p/s/k/x/r/e/c jumps to each section)

Proxies page
- Server-side: merge static site proxy routes with instance routes and sort
  by domain (internal/api/proxies.go, internal/store/static_sites.go)
- ProxyRoute gains a Source field ("instance" | "static_site")
- Frontend adds source filter tabs and per-source labels/badges
