v0.19.0 frontend: /docs/* route tree + flyout nav + sessions browser

Reorganizes the /docs surface from a single DOCS.md route into a hub
with a left-side flyout nav and three new sub-routes for the on-site
sessions browser (roadmap item #30):

  /docs                      → redirect to /docs/user-guide
  /docs/user-guide           → existing DOCS.md content
  /docs/sessions             → redirect to /docs/sessions/about
  /docs/sessions/about       → README.md of ohm-session-history
  /docs/sessions/<NNNN>      → per-session transcript index
  /docs/sessions/<NNNN>/<f>  → per-transcript view

The flyout is a persistent left sidebar on desktop and a slide-out
drawer on mobile (toggled by a ☰ button in the docs header). Its
session list is driven by the /api/docs/sessions/manifest fetch —
loading shows a skeleton; 502 shows an inline retry; empty manifest
shows only the "About" row.

Each sub-route owns its own empty-state / error handling:
  - 404 transcripts render "This transcript isn't published yet"
    with a link back to the parent session index, no JS crash.
  - 502 (gitea unreachable) renders a retry button.
  - Manifest 404 is mapped to {} server-side so the flyout renders
    cleanly with no error banner when no sessions are published yet.

Analytics (per SPEC §21):
  - new EVENTS.DOC_VIEWED ("Doc Viewed") fires on each sub-route
    mount with `section`: 'user-guide' | 'sessions/about' |
    'sessions/<NNNN>' | 'sessions/<NNNN>/<filename>'.
  - every interactive nav element carries aria-label +
    data-amp-track-name so autocapture rows are readable.

The existing v0.14.0 Docs.jsx component is dropped — its content
moved verbatim into DocsUserGuide.jsx; the new layout subsumes the
back-button + signed-out home affordances it used to carry. All
four new sub-routes reuse the existing MarkdownPreview renderer
(marked + mermaid lazy-load) so no second markdown library lands.
