feat(webui): evolve application shell for Phase 1 console IA (Closes #638)

Introduce a single nav-config module (webui/nav.py) driving grouped
navigation across the epic #631 Phase 1 information architecture:
Health, Traffic, Runtime/Sessions, Projects, Inventory, Timeline,
Policy (placeholder), and Insights (placeholder). The shell header now
carries a read-only environment badge (local/remote from WEBUI_HOST), a
mode: read-only badge, and a Docs link. Home summarizes the console
purpose, lists the Phase 1 surfaces by group, and links the MVP legacy
pages.

Not-yet-implemented surfaces (/sessions, /inventory, /timeline,
/policy, /insights) resolve to graceful read-only stub pages rather than
404s; their backing views land in later child issues of #631 (inventory
surfaces backed by #636). Mutating methods on stub routes still fail
closed with read-only-mvp. No privileged action controls are added.

Adds tests/test_webui_shell.py covering nav groups, badge presence,
environment classification, docs link, stub routes (200 + read-only),
and home content. Updates docs/webui-local-dev.md with the new routes
and a Phase 1 shell section.

## Application shell — Phase 1 (#638)
The console shell (`webui/layout.py`) renders a grouped navigation driven by a
single nav-config module, `webui/nav.py`. Nav groups follow the epic #631
Phase 1 information architecture: **Health, Traffic, Runtime/Sessions,
Projects, Inventory, Timeline, Policy** (placeholder), and **Insights**
(placeholder). Live views and Phase 1 placeholders (`stub`) are declared in one
place so the layout and the route table cannot drift.
The header carries two read-only status badges — an **environment** badge
(`local` for loopback binds, `remote` otherwise, derived from `WEBUI_HOST`) and
a **mode: read-only** badge — plus a **Docs** link to this document. No
privileged action controls are present in the Phase 1 shell.
Not-yet-implemented surfaces (`/sessions`, `/inventory`, `/timeline`,
`/policy`, `/insights`) resolve to graceful read-only stub pages instead of
404s; their backing views land in later child issues of #631 (the inventory
surfaces are backed by #636). Mutating methods on stub routes still fail closed
with `read-only-mvp`.
## Deployment boundary (#435)
MVP serves on loopback by default. Binding `0.0.0.0` or `::` is **refused**
