docs: document the settings surface and repoint the moved settings paths

A docs pass landed in this worktree while the preview was up (a respawn loop on
the throwaway session it was serving), and it is the documentation this work
needed, so it is reviewed and kept rather than thrown away.

- docs/architecture-invariants.md gains a "Settings surface" section: the one
  `:is()` scope and why the id-only list preserves specificity, the anatomy,
  the two meanings of the rail, the deliberate two sizes, the phone strip, the
  Add Case adapter, the flex-summary chevron trap, the Respawn ordering, the
  retired tab chrome, and the live preview's clone-the-chip-icon rule.
- Settings paths are repointed everywhere they moved: Display -> Header &
  Panels (header buttons, cron, multi-monitor, response viewer, file viewer),
  Settings -> App Settings -> System -> Updates, Panels -> Header & Panels ->
  Cross-session features (Read My Mind), Display -> Terminal & Input (gesture
  control), Claude Model -> Models -> New Claude sessions.
- Stale counts refreshed (route modules, frontend modules, type files, config
  files) and the typecheck script named.
- browser-testing-guide gains the three modal ids and the `set-*` selectors.
- The styles.css block comment covers all three modals.

Two claims it got wrong are corrected here: an external-CLI session opens
Session Options on the Session tab (`switchOptionsTab('context')`), not
Summary - measured in the browser - and the Cron toggle lives under Header &
Panels -> Scheduling, with no "Header Displays" step under it any more.

 ## More Features
 
 - **Background daemon & service install** — `codeman web -d` runs the server detached with a pidfile, `~/.codeman/web.log`, and verified startup (it polls the server until it answers, so a port clash never reads as success); `codeman service install` writes a systemd user unit (Linux) or LaunchAgent (macOS) with your shell's PATH baked in, so an nvm or Homebrew `node`, `tmux` and `claude` are actually found. Secrets are never written into unit files

 - **Clone a GitHub repo as a case** — paste a repository URL into **Add Case → Clone Repo** and Codeman clones it into `~/codeman-cases/<name>` and registers it as a normal case, ready to run an agent in. It preflights the URL while you type (tells you whether it can be cloned anonymously and offers the repo's real branches and tags for the optional branch/tag field), fills the case name in from the URL, and lets you pick which CLI the Run button should use. Public repositories over `https://`; Codeman never collects or stores credentials
 - **Multi-CLI** — run **Claude Code**, **OpenCode**, **Codex**, **Antigravity**, or **Gemini** per session; env-var prefixes auto-gate (`CLAUDE_CODE_*` vs `OPENCODE_*` vs `CODEX_*` vs `ANTIGRAVITY_*` vs `GEMINI_*`/`GOOGLE_*`). See [`docs/opencode-integration.md`](docs/opencode-integration.md)
 - **Docker sessions** — run a case inside an isolated, hardened container. One checkbox on **Create New** spins up a container with sensible defaults and starts the agent inside it; multiple sessions share one per-case container; export a container + its workspace to a portable `.tar.gz` to move it to another machine.

 - **Loopback by default** — the server binary binds `127.0.0.1`, reachable only from the same machine, so the no-password default is safe out of the box (the guided installer asks about network access and configures the binding + password for you).

 - **Optional auth, real sessions** — HTTP Basic via `CODEMAN_USERNAME` (default `admin`) / `CODEMAN_PASSWORD`. Success issues an opaque 256-bit `codeman_session` cookie (`randomBytes(32)`) — validated server-side, not client-signed, so it can't be forged offline (24h TTL, auto-extend, device-context audit log)
 - **Per-IP rate limiting** — 10 failed attempts → `429` with `Retry-After` (15-min decay). A valid cookie or correct password recovers _immediately_ even while an attacker hammers the same IP — important because all tunnel traffic shares one loopback IP. QR auth has its own separate limiter
