feat(dashboard): close 3 of 5 Phase 5 P2 mitigation items (allow-list, projectPath, audit-log)

Browse Source 
Closes the three Phase 5 P2 follow-ups from the DEPLOYMENT.md
mitigation roadmap that don't need infra changes. Two P2 items remain
(non-root container, docker-proxy daemon) — both genuinely need
container/orchestration work and stay queued.

1. Allow-list shell wrapper (P1)
   New `lib/shell.ts`:
     - `execAllowed(cmd, args, opts)` — `execFile`-only, no shell, no
       interpolation. Single escape hatch for ad-hoc invocations.
     - `dockerRestart(name)` — name validated against
       `[a-zA-Z0-9][a-zA-Z0-9._-]{0,127}`; throws InvalidShellArgError
       on anything else (including non-strings, shell metacharacters,
       command-substitution attempts). Tests cover all of these.
     - `dockerPrune(kind, {all?})` — kind constrained to
       {container,image,volume,builder}; `--all` only valid for image.
     - `runBashScript(path, args, {allowedRoots})` — script path AND
       cwd both checked against allowed roots; rejects `..` escapes
       and prefix-matching siblings (`/opt/projects-evil` vs
       `/opt/projects`).
     - `runNpmScript(script, {cwd, allowedRoots})` — script ∈
       {typecheck,lint,build,test,test:run,start}; cwd inside roots.
   17 unit tests cover every rejection path. Module added to the
   coverage gate (≥95% lines).

   Migrated highest-risk callers off template-literal `exec`:
     - `vm/repository.ts:restartContainer` → `dockerRestart`. Was
       previously `await execAsync(\`docker restart "${name}"\`)`
       with only a regex check; now goes through the wrapper.
     - `system/repository.ts:dockerCleanup` → `dockerPrune` per kind
       + `execAllowed` for `docker system df`. Drops the array of
       template-literal command strings entirely.
     - `code-quality/repository.ts` → `runNpmScript` for every
       lifecycle invocation. cwd is now the resolved (normalised,
       `..`-collapsed) path, not the raw input.

2. projectPath validation for /code-quality/check (P1)
   `runCodeQualityCheck` now calls
   `assertPathInAllowedRoots(projectPath, getAllowedRoots())` before
   any subprocess spawns. `getAllowedRoots()` reads
   `CODE_QUALITY_ALLOWED_ROOTS` (colon-separated env, defaults to
   `/opt/bytelyst`). Rejection happens with a clear error message
   listing the configured roots so operators know what to allow.

3. Audit-log every privileged shell-out (P2)
   `audit/types.ts` extended: `action` now includes `'shell-exec'`,
   `entityType` includes `'host'`. The migration is additive — old
   audit rows still validate.

   Three privileged routes now write a `shell-exec` audit row with
   actor (authUserId / authRole), entity id, and a sanitized details
   payload before responding:
     - `POST /docker/cleanup` — `entityId: docker-cleanup:<type>`,
       details include {type, force, freedSpace}.
     - `POST /vm/cleanup` — `entityId: vm-cleanup:<mode>`.
     - `POST /vm/containers/:name/restart` — `entityId:
       container-restart:<name>`, details include {success, message}.
       Audited even on failure so attempted privileged actions are
       still recorded.
   Audit writes are best-effort — a Cosmos hiccup logs a warn but
   never fails the request the operator was running.

Verified: backend typecheck ✅, 74/74 unit tests ✅ (17 new for
shell.ts + audit changes), 7/7 E2E ✅, lint 0 errors, coverage gate
≥95% lines on every gated file (which now includes shell.ts).

### Mitigation roadmap (incremental, not all at once)
- [ ] **P1 (next):** Allow-list wrapper around shell-outs. Centralize
`docker`/`bash`/`npm` invocations behind a small `lib/shell.ts` that
validates the arg vector against a per-command schema (e.g.
`docker.restart(name)` rejects names not matching `^[a-zA-Z0-9._-]{1,128}$`).
- [ ] **P1:** Validate `/code-quality/check`'s `projectPath` against a
configured set of allowed roots.
- [ ] **P2:** Audit-log every shell-out (command + arg vector + actor + result).
- [x] **P1:** Allow-list wrapper around shell-outs. *(`lib/shell.ts` ships with
`execAllowed` (no shell, just `execFile` with an explicit argv) plus
per-command helpers — `dockerRestart(name)` validates against
`[a-zA-Z0-9][a-zA-Z0-9._-]{0,127}`, `dockerPrune(kind, {all?})` validates
kind ∈ {container,image,volume,builder} and rejects `--all` on non-image,
`runBashScript(path, args, {allowedRoots})` and `runNpmScript(script,
{cwd, allowedRoots})` lock both the script path and cwd to a configured
set of roots. 17 unit tests cover the rejection paths; `vm/restartContainer`
and `system/dockerCleanup` migrated. Module covered by the test:coverage
gate (≥95% lines).)*
- [x] **P1:** Validate `/code-quality/check`'s `projectPath` against a
configured set of allowed roots. *(`runCodeQualityCheck` now calls
`assertPathInAllowedRoots(projectPath, getAllowedRoots())` before any
lifecycle script runs; `getAllowedRoots()` reads
`CODE_QUALITY_ALLOWED_ROOTS` (colon-separated) with a default of
`/opt/bytelyst`. The path is also re-resolved (normalised, `..`
collapsed) before being passed to `runNpmScript`, which lifts it to its
own argv slot — no shell interpolation.)*
- [x] **P2:** Audit-log every shell-out (command + arg vector + actor + result).
*(Audit schema extended with `action: 'shell-exec'` + `entityType: 'host'`.
`POST /docker/cleanup`, `POST /vm/cleanup`, `POST /vm/containers/:name/restart`
now write a Cosmos audit row including the actor (`authUserId`/`authRole`),
entity id (`docker-cleanup:<type>` etc.), and a sanitized details payload.
Audit writes are best-effort — a Cosmos hiccup logs a warn but never
fails the request.)*
- [ ] **P2:** Run the backend container as a non-root user with `docker` group
membership; rebuild the Dockerfile accordingly.
- [ ] **P3:** Move from `docker.sock` to a thin daemon (`docker-proxy`-style)
